    • A solid state laser (300) includes an optical waveguide and a laser cavity (302) including at least one subwavelength mirror (305, 310) disposed in or on the optical waveguide (312). A plurality of photoluminescent nanocrystals (317) are disposed in the laser cavity (302). The reflective subwavelength mirror (305, 310) can be a pair of subwavelength resonant gratings (SWG), a pair of photonic crystal structures (PC), or a distributed feedback structure. In the case of a pair of mirrors (305, 310), a PC which is substantially transmissive at an operating wavelength of the laser can be disposed in the laser cavity (302) between the subwavelength mirrors (305, 310) to improve the mode structure, coherence and overall efficiency of the laser (300). A method for forming a solid state laser (300) includes the steps of providing an optical waveguide (312), creating a laser cavity (302) in the optical waveguide (312) by disposing at least one subwavelength mirror (305, 310) on or in the waveguide (312), and positioning a plurality of photoluminescent nanocrystals (317) in the laser cavity (302).

    • A polarization sensitive filter includes a first sub-wavelength resonant grating structure (SWS) for receiving incident light, and a second SWS. The SWS are disposed relative to one another such that incident light which is transmitted by the first SWS passes through the second SWS. The filter has a polarization sensitive resonance, the polarization sensitive resonance substantially reflecting a first polarization component of incident light while substantially transmitting a second polarization component of the incident light, the polarization components being orthogonal to one another. A method for forming polarization filters includes the steps of forming first and second SWS, the first and second SWS disposed relative to one another such that a portion of incident light applied to the first SWS passes through the second SWS. A method for separating polarizations of light, includes the steps of providing a filter formed from a first and second SWS, shining incident light having orthogonal polarization components on the first SWS, and substantially reflecting one of the orthogonal polarization components while substantially transmitting the other orthogonal polarization component. A high Q narrowband filter includes a first and second SWS, the first and second SWS are spaced apart a distance being at least one half an optical wavelength.
