Picosecond and sub-picosecond pulse generation in semiconductor lasers
Generation of short optical pulses in semiconductor lasers is of practical interest for an increasing number of applications. It is also of fundamental interest because of its tight relation with the field of semiconductor laser dynamics. After an introductory review, we compare the performances of gain-switching, Q-switching and mode-locking techniques. The comparison is illustrated by experim...
متن کاملOutput properties of short-pulse gain-switched lasers.
A formalism is derived for analyzing the spectral and temporal properties of gain-switched lasers. The development of the longitudinal mode structure from spontaneous emission, limiting linewidths, and over-all spectral characteristics are considered in detail; and applications are discussed.
متن کاملSpectral dynamics of picosecond gain-switched pulses from nitride-based vertical-cavity surface-emitting lasers
Short pulses generated from low-cost semiconductor lasers by a simple gain-switching technique have attracted enormous attention because of their potential usage in wide applications. Therein, reducing the durations of gain-switched pulses is a key technical point for promoting their applications. Therefore, understanding the dynamic characteristics of gain-switched pulses is highly desirable. ...
متن کاملTwo-dimensional simulation of quantum well lasers
We describe a two-dimensional model for quantum-well lasers that solves self-consistently the electrical and optical equations. The model includes a wavelengthand position-dependent gain function which is derived from a quantum-mechanical calculation. We have also incorporated the effects of strain into the model, through an anisotropic parabolic band approximation of the band structure from a ...
متن کاملPicosecond microwave pulse generation
Picosecond duration X-band microwave pulses have been generated using a laser-activated photoconductive switch. These pulses have been used to observe the microwave reflection from optically excited germanium. The reflection measurements indicate that the microwave pulse has a full width at half-maximum of 50 ps and is synchronized with picosecond precision to the laser pulse. A high-resolution...
