Abstract:

A method of pumping an optical resonator includes directing light generated by a pumping light at the optical resonator, exciting a propagating surface state of the optical resonator at an interface of the optical resonator, and changing a propagating frequency of the light proximate the interface, where the changed frequency corresponds to a propagation frequency of the surface state. The optical resonator includes a photonic crystal and a material, where the interface is formed between the photonic crystal and the material.

International Classification:

G09F 7/20

Abstract:

A sign assembly have a chassis assembly for supporting indicia plates and for providing proper horizontal alignment of the indicia plates. The chassis assembly includes two chassis members having a medial receptacle for receipt of a support panel and a receptacle for receipt of alignment members. The indicia plates include mating members on distal edges for cooperating with the chassis member alignment members. The mating members and alignment members have cooperating surface configurations to facilitate proper indicia plate horizontal alignment. A tamper resistant assembly prevents unintentional removal of the indicia plates from the chassis assembly.

Abstract:

A method of pumping an optical resonator includes directing light generated by a pumping light at the optical resonator, exciting a propagating surface state of the optical resonator at an interface of the optical resonator, and changing a propagating frequency of the light proximate the interface, where the changed frequency corresponds to a propagation frequency of the surface state. The optical resonator includes a photonic crystal and a material, where the interface is formed between the photonic crystal and the material.
