We present both experimental and theoretical investigations of the operation of a harmonically modelocked erbium fiber ring laser stabilized by an intracavity bit-rate etalon. Our model analyzes the effects of cavity components and operating paramete

Time‐resolved photoluminescence has been used to study the decay of photoexcited carriers in bulk InSb at 2 K. The recombination occurs as a two step process exhibiting a fast and a slow decay. The fast decay, corresponding to band‐to‐band reco

We demonstrate microwave modulation of an optical beam by using the electro-optic effect in total internal reflection near the critical angle. An internally reflected mode-locked laser beam and a microwave field electrooptically interact near the sur

Applications such as situational awareness are becoming more prevalent in highly dynamic tactical mesh networks and are placing high demand on existing RF network capacity. These applications require high aggregate data capacity but have some flexibi

We investigate thermally induced changes in the index of refraction of BaTiO(3) that are caused by optical absorption. We show that the absorption of a 900-mW optical beam will change the surface temperature of a BaTiO(3) crystal by more than 40 degr

We present a novel optical bit-pattern-recognition technique that uses erbium-doped fiber at room temperature. Counterpropagating beams write a patterned gain-depletion grating in pumped erbium-doped fiber. This grating, recorded in the erbium gain m

We show that a fiber Bragg grating filter improves the bit-error-rate (BER) performance of a semiconductor-optical-amplifier for return-to-zero (RZ) wavelength conversion. A 14-dB reduction in power penalty was obtained at 10.6 Gb/s.

Wavelength converters that employ cross-gain modulation (XGM) in semiconductor optical amplifiers (SOAs) are limited in bit rate by the amplifier's pattern dependent response. We substantially suppress this pattern dependence by converting the phase
