Integrated waveguide-DBR microcavity opto-mechanical system
Optics Express, 2011 Cavity opto-mechanics exploits optical forces acting on mechanical structures. Many opto-mechanics demonstrations either require extensive alignment of optical components for probing and measurement, which limits the number of opto-mechanical devices on-chip; or the approaches limit the ability to control the opto-mechanical parameters independently ...

Chirp-Compensated DBR Lasers for TWDM-PON Applications
IEEE Photonics Journal, 2015 We propose a novel chirp compensation scheme for directly modulated three-section distributed Bragg reflector (3s-DBR) lasers in applications of the time- and wavelength-division multiplexed passive optical network systems.

Discretizing the Heston Model: An Analysis of the Weak Convergence Rate
, 2016 In this manuscript we analyze the weak convergence rate of a discretization scheme for the Heston model. Under mild assumptions on the smoothness of the payoff and on the Feller index of the volatility process, respectively, we establish a weak ...

High-reflectivity broadband distributed Bragg reflector lattice matched to ZnTe
, 2009 We report on the realization of a high quality distributed Bragg reflector with both high and low refractive index layers lattice matched to ZnTe. Our structure is grown by molecular beam epitaxy and is based on binary compounds only. The high refractive

Using Bayesian Optimization to Increase the Efficiency of III‐V Multijunction Solar Cells
Advanced Theory and Simulations, Volume 9, Issue 2, February 2026.Technology Computer Aided Design (TCAD) modeling is crucial for designing complex optoelectronic devices like III‐V multijunction solar cells. Bayesian optimization is proposed as a robust method to address challenges in optimizing costly black‐box TCAD solvers.
