Optical efficiency and gain dynamics of modelocked semiconductor disk lasers.

open access: goldOptics Express, 2017
Compact optically pumped passively modelocked semiconductor disk lasers (SDLs) based on active quantum wells (QWs) such as vertical external-cavity surface-emitting lasers (VECSELs) or modelocked integrated external-cavity surface-emitting lasers ...

Numerical and Experimental Analysis of Optical Frequency Comb Generation in Gain-Switched Semiconductor Lasers

open access: greenIEEE Journal of Quantum Electronics, 2019
We have performed a systematic experimental and simulation analysis of the optical frequency combs generated by gain-switching single mode laser diodes, either free-running or subjected to optical injection.

All-optical half adder using cross gain modulation in semiconductor optical amplifiers

open access: goldOptics Express, 2006
By using the gain nonlinearity characteristics of semiconductor optical amplifier, an all-optical binary half adder at 10 Gbps is demonstrated. The half adder operates in a single mechanism, which is cross gain modulation. The half adder utilizes two logic functions of SUM and CARRY, which can be demonstrated by using XOR and AND gates, respectively ...

Gain-Clamped Quantum Dot Semiconductor Optical Amplifiers [PDF]

open access: bronzeInternational 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

Adjustable Gain-Clamped Semiconductor Optical Amplifiers (AGC-SOA)

open access: bronzeAsia Communications and Photonics Conference, 2012
The presentation will describe the design and performance of an adjustable gain-clamped semiconductor optical amplifier (AGC-SOA) designed to maximize the output saturated power while adjusting gain across a wide dynamic range. This device is shown to modulate gain at rates that are compatible with packet to packet equalisation.

Frequency dynamics of gain-switched injection-locked semiconductor lasers [PDF]

open access: yes, 1997
The frequency dynamics of gain-switched singlemode semiconductor lasers subject to optical injection is investigated. The requirements for low time jitter and reduced frequency chirp operation are studied as a function of the frequency mismatch between ...
