A method of determining parameters of a critically coupled microring resonator includes modeling a coupled portion of the microring resonator as a U-shaped waveguide spaced apart from a straight waveguide by a gap and selecting a straight waveguide width and a gap size to optimize an output coupling ratio between the U-shaped waveguide and the straight waveguide.

摘要： In one aspect of the present invention, an electric-field-enhancement structure is disclosed. The electric-field-enhancement structure includes a substrate and an ordered arrangement of dielectric particles having at least two adjacent dielectric particles spaced from each other a controlled distance. The controlled distance is selected so that when a resonance mode is excited in each of the at least two adjacent dielectric particles responsive to excitation electromagnetic radiation, each of the resonance modes interacts with each other to result in an enhanced electric field between the at least two adjacent dielectric particles. Other aspects of the present invention are electric-field-enhancement apparatuses that utilize the described electric-field-enhancement structures, and methods of enhancing an electric field between adjacent dielectric particles.

摘要： Vertical-cavity surface-emitting lasers (“VCSELs”) and VCSEL arrays are disclosed. In one aspect, a surface-emitting laser includes a grating layer having a sub-wavelength grating to form a resonant cavity with a reflective layer for a wavelength of light to be emitted from a light-emitting layer and an aperture layer disposed within the resonant cavity. The VCSEL includes a charge carrier transport layer disposed between the grating layer and the light-emitting layer. The transport layer has a gap adjacent to the sub-wavelength grating and a spacer region between the gap and the light-emitting layer. The spacer region and gap are dimensioned to be substantially transparent to the wavelength. The aperture layer directs charge carriers to enter a region of the light-emitting layer adjacent to an aperture in the aperture layer and the aperture confines optical modes to be emitted from the light-emitting layer.
