Plasmon-induced transparency (PIT) in a compact plasmonic resonator structure, which consists of a metal– dielectric–metal waveguide with an aperture-coupled square cavity and a slot resonator, is investigated theoretically and numerically. We find the transparency window and the delay of slow light in this structure can be controlled at a fixed wavelength by carefully adjusting the geometrical parameters...
We describe the design concepts, performance features and application capabilities of on-chip laser sources for regrowth-free multi-guide vertical integration in indium phosphide, based on the compatibility requirements of this monolithic photonic integration platform.
A model to analyze longitudinal mode selection in high-order laterally coupled DFB lasers is developed and used to verify an ability to control the complex coupling resulting in a single-frequency lasing by manipulating the grating shape.
An integrated optically pre-amplified photodetector, featuring waveguide gain and absorption sections defined on the same active waveguide layers atop a common passive waveguide, is reported. The device demonstrates high responsivity while exhibiting little polarization sensitivity.
