Speed Enhancement of a Single-Mode FP-LD-Based Switch Using the Weak-Lock Technique

IEEE Photonics Journal, 2014
A technique called weak-lock (WL) has been proposed and applied to a simple optical on/off switch to increase its working speed from 1 to 12 Gb/s with clear output waveforms, whereas the required injection power is decreased.

Fundamentals and applications of spatial dissipative solitons in photonic devices : [Chapter 6] [PDF]

, 2009
We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐localized optical excitations sitting on a uniform, or quasi‐uniform, background in a dissipative environment like a nonlinear optical cavity.

Investigation of Self-Injection Locked Visible Laser Diodes for High Bit-Rate Visible Light Communication

IEEE Photonics Journal, 2018
We report on self-injection locking in InGaN/GaN (blue/green) and InGaP/AlGaInP (red) visible-light laser diodes. The free-space optical feedback path was accomplished via an external mirror. The effect of injection current, optical power injection ratio,

Injection locking of an electro-optomechanical device

, 2017
The techniques of cavity optomechanics have enabled significant achievements in precision sensing, including the detection of gravitational waves and the cooling of mechanical systems to their quantum ground state. Recently, the inherent non-linearity in

Stable mode-locked pulses from mid-infrared semiconductor lasers [PDF]

, 2009
We report the unequivocal demonstration of mid-infrared mode-locked pulses from a semiconductor laser. The train of short pulses was generated by actively modulating the current and hence the optical gain in a small section of an edge-emitting quantum ...

Supermodes of high-repetition-rate passively mode-locked semiconductor lasers [PDF]

, 1996
We present a steady-state analysis of high-repetition-rate passively mode-locked semiconductor lasers. The analysis includes effects of amplitude-to-phase coupling in both gain and absorber sections. A many-mode eigenvalue approach is presented to obtain

Design and analysis of a reconfigurable discrete pin tooling system for molding of three-dimensional free-form objects [PDF]

, 2010
This paper presents the design and analysis of a new reconfigurable tooling for the fabrication of three-dimensional (3D) free-form objects. The proposed reconfigurable tooling system comprises a set of matrices of a closely stacked discrete elements (i ...

Critical Behavior of Light

, 2005
Light is shown to exhibit critical and tricritical behavior in passive mode-locked lasers with externally injected pulses. It is a first and unique example of critical phenomena in a one-dimensional many body light-mode system. The phase diagrams consist
