Recently, integrated optics has become a functional platform for implementing machine learning algorithms and, in particular, neural networks. Photonic integrated circuits can straightforwardly perform vector-matrix multiplications with high efficien

Epsilon-near-zero (ENZ) materials have demonstrated enhanced nonlinear optical interactions and efforts to push performance are underway. Beginning with the origin of nonlinearities in ENZ, we highlight avenues for improvement using nanostructures an

We propose a lattice-matched Ge/GeSiSn quantum cascade detector (QCD) capable of operating in the longwave infrared. The optical absorption and carrier transport based on intersubband transitions all occur within the L-valley of the conduction band o

We develop a theory describing the operation of an opto-mechanical oscillator as a phonon laser using a set of coupled equations that is analogous to the standard set of laser rate equations. We show that laser-like parameters that characterize gain,

We have used surface micromachining to fabricate suspended InGaAs quantum well waveguides that are supported by lateral tethers. Their enhanced electro-optical and nonlinear-optical properties will be discussed.

The use of fluorescent dyes which can be attached to specific cellular components as biological markers has become a well- established biomedical technique in recent years [1]. When optically stimulated, these dyes emit a characteristic fluorescence,

As excitation (laser) intensity increases, the average distance between the occupied donors and acceptors decreases. As a result, due to the decrease of Coulomb interaction energy between the recombined donors and acceptors, the donor-acceptor pair (

Ever since the inception of lasers there has been a consistent effort towards reducing their threshold which in general can be achieved by two means: reduction of the active region size and eliminating the residual absorption. Rapid progress in the r
