US Patent:

41677447, Sep 11, 1979
Filed:

Mar 23, 1978
Appl. No.:

5/889354
Inventors:

Paul Nyul - New Holland PA
Assignee:

RCA Corporation - New York NY
International Classification:

H01L 2714
US Classification:

357 17
Abstract:

An electroluminescent semiconductor element is mounted in a housing with an optical fiber extending from the semiconductor element through an opening in the housing and projecting slightly beyond the housing. A plastic material completely surrounds the projecting portion of the optical fiber except for the adjacent end surface of the fiber. The plastic material secures the fiber to the housing, rigidly supports the projecting end portion of the fiber, and seals the opening in the housing through which the fiber extends. The end surface of the fiber is polished to permit emission of light emanating from the semiconductor element.

Appl. No.:

6/111814
Inventors:

Paul Nyul - New Holland PA
Frederick R. Hughes - Lancaster PA
Assignee:

RCA Corporation - New York NY
International Classification:

H01U 2348
US Classification:

357 68
Abstract:

An article having two parts bonded together includes an intermediate member between opposed surfaces of the two parts. The intermediate member has a plurality of openings therethrough which are filled with a bonding material. The opposed surfaces of the two parts engage opposed surfaces of the intermediate member and the bonding material is adhered to the opposed surfaces of the two parts to bond them together. The intermediate member provides control of the spacing between the two parts and the positional relationship of the two parts.

US Patent:

43808620, Apr 26, 1983
Filed:

Nov 16, 1981
Appl. No.:

6/322007
Inventors:

Paul Nyul - Lancaster PA
Assignee:

RCA Corporation - New York NY
International Classification:

H01L 2128
H01L 21302
H01L 2158
H01S 319
US Classification:

29569L
Abstract:

The invention is an improved method of fabricating a semiconductor laser which comprises bonding an electrically conducting sheet to a metallized surface of a strip of semiconductor material prior to separating the strip into one or more laser chips. The invention provides a simplified method of fabricating a laser having reduced resistive heating in the contact and improved uniformity of electrical current flow.

US Patent:

43319386, May 25, 1982
Filed:

Aug 25, 1980
Appl. No.:

6/180898
Inventors:

Albert C. Limm - Lancaster PA
James T. O'Brien - Leola PA
Thomas V. Colgrove - Leola PA
Paul Nyul - New Holland PA
Assignee:

RCA Corporation - New York NY
International Classification:

H01S 319
US Classification:

372 50
Abstract:

An improved semiconductor injection laser diode array having reduced interaction between the elements of the array. The array comprises a substrate, an active layer and a capping layer with a separate electrical contact to the capping layer for each element of the array and a common electrical contact to the substrate. The reduced interaction is obtained by regions of higher electrical conductivity extending through the substrate towards the p-n junction from those portions of the substrate surface opposed to the contacts to the capping layer and by separate electrical contacts to each of these higher conductivity regions. The higher conductivity regions provide a lower resistivity path for current flowing through the p-n junction, thus reducing current spreading.

US Patent:

44796986, Oct 30, 1984
Filed:

May 17, 1982
Appl. No.:

6/379097
Inventors:

William C. Landis - Lancaster PA
Paul Nyul - New Holland PA
Assignee:

RCA Corporation - New York NY
International Classification:

G02B 726
US Classification:

350 9620
Abstract:

A light emitting assembly comprising a light emitting device, an optical fiber and an optical coupling medium which is contacted to both a facet of the light emitting device and an end face of the fiber and whose maximum diameter is comparable to the diameter of the end face of the fiber. The invention is also a method of making this light emitting assembly which comprises positioning the end face of the optical fiber adjacent to the emitting portion of the facet, interposing an optical coupling medium between the facet and the end face of the fiber and increasing the space between the facet and the end face of the fiber until the maximum amount of light is coupled into the fiber.

Assignee:

RCA Corporation - New York NY
International Classification:

H01L 2714
H01L 3100
H01L 2302
US Classification:

357 30
Abstract:

A fiber-optic face plate is mounted across the light emitting surface of an electroluminescent semiconductor element so that the light emitted from the semiconductor element passes through the face plate. The electroluminescent semiconductor element may be enclosed in a housing with the face plate extending across and being hermetically sealed to an end of the housing.

Appl. No.:

6/699557
Inventors:

Paul Nyul - New Holland PA
Rudolph H. Hedel - West Windsor NJ
Assignee:

RCA Corporation - Princeton NJ
International Classification:

H01J 502
H05B 3302
US Classification:

313110
Abstract:

The invention is an improved electrooptic assembly which comprises an electrooptic device mounted on a header and enclosed by a cover with a light-transmissive window mounted therein. The header includes a base plate with two major surfaces and a minor surface connecting the major surfaces with a segment of the cover attached to the minor surface. The minor surface is non-perpendicular to the major surfaces, thus allowing adjustment of the position of the window to achieve optimum emission or detection.

Filed:

Aug 17, 1977
Appl. No.:

5/825473
Inventors:

James T. O'Brien - Leola PA
Albert C. Limm - Lancaster PA
Paul Nyul - New Holland PA
Vincent S. Tassia - York PA
Assignee:

RCA Corporation - New York NY
International Classification:

G02B 2700
US Classification:

250551
Abstract:

Mounted on the metallic base member of a radiation emitter-detector package is a mounting block having a first projection, and a second projection spaced from the first projection. A radiation detector is on the first projection and a semiconductor electroluminescent device, i. e. , a radiation emitter, is on the second projection such that the plane of the recombination region of the electroluminescent device is substantially perpendicular to the radiation incident surface of the radiation detector. The electroluminescent device is of the type having a primary emission and a secondary emission in a direction different from the primary emission. A radiation emitter-detector package as described is ideally suited to those applications wherein the secondary radiation of the electroluminescent device is fed into a feedback circuit regulating the biasing current of the electroluminescent device.
