Pound-Drever-Hall locking is a high performance technique for laser frequency stabilization. Radio frequency optical modulation combined with electronic demodulation provides a feedback signal to lock a laser's frequency to a cavity resonance. Althou

We frequency stabilize a fiber laser for use in low-frequency sensing applications. Using a radio frequency locking technique, an Erbium-doped single longitudinal mode fiber laser is stabilized to a Mach-Zehnder interferometer. The low-frequency fibe

Compact superstructure fibre Bragg gratings for the generation of ultra-high speed optical pulse bursts are reported. The gratings are equivalent in response to multi-pass superimposed chirped fibre Bragg gratings (SI-CFBGs), but an arbitrary sequenc

The ability to slow down and delay optical pulses is an intriguing physical phenomenon with significant applications, such as in telecommunications. It is essential for these applications that the phenomenon has enough bandwidth, so that it can respo

We demonstrate that chromatic dispersion and group delay ripple limit the performance of all-optical regeneration based on self-phase modulation. The level of degradation depends in detail on the type of phase distortions introduced. The regenerator

We demonstrate integrated all-optical 2R regenerators based on Kerr optical nonlinearities (subpicosecond response) in chalcogenide glass waveguides with integrated Bragg grating filters. By combining a low loss As/sub 2/S/sub 3/ rib waveguide with a

We present a bandwidth-adjustable filter that enables reconfiguration of the bit rate of optical subsystems. This filter is bandwidth-adjustable, wavelength-tunable, and maintains zero dispersion as the bandwidth and wavelength are varied. It also ha

A system design is presented which allows a voltage controlled oscillator (VCO) to be tuned to an arbitrary frequency between 78 and 94 MHz with an accuracy better than 1 kHz (10 ppm). The temperature coefficient is on the order of 1 kHz/K, giving a
