We report on electrically pumped SiGeSn microring lasers, strain relaxed by means of undercutting the underlying germanium virtual substrate. Opening of the gain stack in the middle of the disks allows additional strain relaxation while maintaining adequate heat sinking to the substrate.

There exist optimal modes for free-space spatial-mode multiplexing with minimum degradation, under a realistic assumption that a transmitter knows the statistics of propagated fields. Using these modes as transmit and receive bases minimizes the complexity of any signal processing for compensating the impact of turbulence.

Narrow linewidth lasers are vital for variety of applications and huge progress in some industries is impossible without the availability of high performance, and spectrally pure lasers. One approach for providing narrow linewidth is employing external cavity lasers. The aim of this study is designing and fabrication of a Distribute Bragg Reflector (DBR) in the UV-Blue wavelength range which can be used as an external feedback of a semiconductor laser. Here we present our simulation and experimental results and our methods for overcoming challenges we have for working in this wavelength range.

Spatially periodic images are useful in a broad range of scientific fields, but are often corrupted by spatial jitter, noise, or missing repetitions. We review recent work on the use of diffraction-induced Talbot self-imaging to recover corrupted periodic images through a passive amplification process.

The nonlinear Schródinger equation which models the pulse propagation in an optical fiber is solved using a physics-informed neural network for the case of soliton propagation. The prediction accuracy, measured against the exact solution (computed using the Runge-Kutta method), is found to be 2.223×10−3.

Electro-optic frequency combs are ideally suited to the rapid and high dynamic interrogation of cavity-based sensors of pressure, temperature, humidity, acoustics, and acceleration. Here we describe novel approaches for the generation and application of such combs in concert with cavity optomechanical devices.

We propose a device composed of stacked thin film optical microcavities to perform compact reconfigurable weighting of wavelength division-multiplexed (WDM) signals. We validate this concept through transfer-matrix simulations of a concrete system composed of rugate filters and phase-change thin films targeting near infrared optical signals.

Mode division multiplexed transmission system performance is affected by linear mode coupling. Mitigating elements such as multiple-input multiple-output (MIMO) equalizers have to be able to follow temporal variations of the coupling. We investigate potential response time requirements for adaptive mitigating elements.
