Using tensile‐strained InGaAs/InGaAsP multiple quantum well material to increase the gain bandwidth, we demonstrate a tuning range of 74.4 nm with sidemode‐suppression ratio of ≳25 dB and as high as 34 dB in a broadly tunable vertical‐coupler

A monolithically integrated photonic circuit with an InGaAs/InGaAsP multiple-quantum-well (MQW) traveling-wave optical amplifier, a Bragg reflection grating-folded noise filter, and an MQW photodetector has been demonstrated. This photonic circuit of

An all fiber, diode-pumped, electrically tunable ring laser is reported. Gain is provided by an erbium-doped fiber and tuning by a Fiber Fabry-Perot etalon. The threshold at 1.566 µm is 2.9 mW, the slope efficiency is 0.15 and the output power is 4.

All-optical demultiplexing and routing are necessary for the implementation of ultra-high bit rate time-division multiplexed communications systems. While existing electro-optic demultiplexers can be operated at extremely high speeds with sinusoidal

A key advantage of a frequency-division-multiple-access (FDMA) optical star network is high-speed simultaneous distribution of information to many users. An attractive implementation [1,2] is to frequency-shift-key (FSK) modulate N laser transmitters

All-optical demultiplexing has been shown with a full-duty-cycle 2.5-Gbit/s signal in a nonlinear fiber Sagnac interferometer. Complete switching of arbitrary pulse patterns in the data stream has been achieved by using two orthogonal polarization st

The concentricity and uniformity of nearly concentric transparent plastic coatings extruded onto optical fibers are determined by a sensitive, nondestructive optical technique. The method is based on the location of unique fringes in the backscattere
