Abstract

Dispersion control in integrated optical systems is an important consideration, especially with the increasing complexity of such systems with many interconnected components. In addition, pulse dispersion control is necessary if semiconductor mode-locked lasers are to produce transform limited pulses[l]. One component that may be employed for these purposes is the integrated chirped Bragg grating (CBG). Integrated gratings are desirable for a number of reasons. They negate any necessity to couple off chip to fibre or bulk optic based dispersion control devices, and moreover, they present a unique bandwidth and dispersion region of operation compared to other technologies; and one which coincides with the typical characteristics of semiconductor mode-locked lasers[2].
