Optical computation using semiconductor optical amplifiers in cross gain modulation

Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003
Summary form only given. The performance of optical networks may be improved by replacing electronics with optics. Computer simulation verifies the feasibility of the proposed scheme. The all-optical logic gates, NOT, NOR, and NOT-XOR were simulated using detailed models and typical parameters for commercial devices for the lasers, SOAs, couplers, and ...

Integral gain in quantum dot semiconductor optical amplifiers

Superlattices and Microstructures, 2013
Abstract In this paper, a new formula of integral gain in quantum dot (QD) semiconductor optical amplifiers (SOAs) depending on the QD states has been derived instead of conventional bulk relation. This formula will pave the way to develop all information in regard to SOA devices.

Nonlinear gain in vertical-cavity semiconductor optical amplifiers

IEEE Photonics Technology Letters, 2003
We report on the wavelength-dependent nonlinear-gain properties of a vertical-cavity semiconductor optical amplifier. A step-like output versus input transfer curve and bistability are found on the long wavelength side of the resonant peak. The characteristics are caused by a dispersive nonlinearity arising from gain saturation in the device.

Terahertz gain in optically excited biased semiconductor superlattices

Applied Physics Letters, 2005
We investigate the terahertz-driven dynamics of excitons in an undoped optically excited biased semiconductor superlattice, including exciton-LO phonon scattering. We calculate the THz gain spectrum for a 820fsTHz pulse when the superlattice is excited by a 590fs optical pulse.

Gate arrays using gain-clamped semiconductor optical amplifiers

OFC/IOOC . Technical Digest. Optical Fiber Communication Conference, 1999, and the International Conference on Integrated Optics and Optical Fiber Communication, 2003
Gate arrays using gain-clamped semiconductor optical amplifiers have been successfully implemented in optical cross-connects for wavelength-division multiplexing routing applications as well as in fast optical packet switching experiments. Recent achievements on these devices will be reviewed.

Gain compression and recovery in semiconductor optical amplifiers

SPIE Proceedings, 2007
A recently reported theory of gain recovery in semiconductor optical amplifiers (SOAs) is extended to develop approximate expressions for the gain compression and recovery time in terms of probe wavelength, unsaturated gain and device length. These results indicate (1) that the gain recovery time should be approximately inversely proportional to the
