    摘要: An optical resonator, a photonic system and a method of optical resonance employ optical waveguide segments connected together with total internal reflection (TIR) mirrors to form a closed loop. The optical resonator includes the optical waveguide segments, an intracavity active element coupled to a designated one of the optical waveguide segments, the TIR mirrors and a photo-tunneling input/output (I/O) port. The photo-tunneling I/O port includes one of the TIR mirrors. The method includes propagating and reflecting the optical signal, or a portion thereof, in the optical resonator, transmitting a portion of the optical signal through the I/O port, and influencing the optical signal. The photonic system includes the optical resonator with optical gain and a source of an optical signal.

    摘要: Planar, polarization insensitive, optical elements to control refraction of transmitted light in free space are disclosed. In one aspect, an optical element includes a substrate having a planar surface, and a polarization insensitive, high contrast, sub-wavelength grating composed of posts that extend from the planar surface. The grating has at least one region. Within each region, cross-sectional dimensions of the posts and/or lattice arrangement of the posts are nonperiodically varied to control refraction of light transmitted through the optical element.
