Gain-Clamped Quantum Dot Semiconductor Optical Amplifiers [PDF]
International Journal of Computer and Electrical Engineering, 2014 The linear optical gain of gain-clamped quantum dot semiconductor optical amplifiers (GCSOAs) has been investigated and studied for different energy detuning, doping concentration and different device length. Our analysis shows that large linear optical gain can be obtained when the laser emits 90meV above the ground state and the amplifier operates at

Harnessing Outer Space for Improved Electrocaloric Cooling
Advanced Functional Materials, EarlyView.A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...
