The metal influence on light emitters has been studied for more than twenty years in semiconductor light emitters. A critical feature is reliance on the correct electromagnetic boundary conditions to understand and predict the performance of either lasers or spontaneous light emitters for which the metal may influence the emission properties. Here we show that nearly (all) recent studies of metal-coupled...
Nanolasers made from III–V active materials and metal-clad cavities have attracted research interest because of the small volume possible with metal nanocavities.1 Proposed applications include intrachip optical interconnects and optical sensors. The metal-clad nanocavities are one of several cavity approaches being studied, and differ from dielectric and semiconductor nanocavities in their high optical...
A compact bandpass filter based on concavo-convex cavity resonators is proposed. The reported resonator is developed from a conventional rectangular cavity resonator by introducing a concave surface. Compared to a conventional rectangular cavity, this new resonator has a low resonant frequency, compact size and a wider relative mono-mode bandwidth. Using the substrate integrated waveguide technique...
Integrated chip-scale electrodes allow isolated control of resonances and phases in optical multi-cavity system. By varying the round trip length, destructive and constructive intra-cavity interferences are observed, representing all-optical analogue to electromagnetically-induced-transparency and superradiance on-chip.
We demonstrate tunable temporal delays in coherently-coupled multi-cavity photonic crystals, in analogue to EIT. We report deterministic control of the group delay, up to 7' the single cavity lifetime, in our CMOS-fabricated chip.
We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows for large tuning (20K/mW), with deterministic resonance control towards all-optical analogue to electromagnetically-induced-transparency on-chip.
We present experimental analysis of weak coupling for monolayer lead sulfide quantum dots coupled to silicon photonic crystal cavities between 4 K and room temperature, as well as power-saturation measurements of dots at 4 K.
This paper presents a proof-of-concept design of a MEMS tunable capacitor for an electromagnetic cavity resonator, by using a circular plate electrostatic zipping actuator. The design, fabrication and mechanical testing of a device containing the actuator and the capacitor will be presented. The testing results are compared with a finite element model using coupled-field analysis with ANSYS.
