Pulse-shaping to reduce the chirping effects of DFB laser

distributed feedback (DFB) laser arrays, where each laser operates at a particular wavelength. The output of these arrays can be joined together by a combiner element, In this thesis, a tunable erbium-doped fiber ring laser (EDFRL) is investigated. Tuning is achieved with the help of an intra-cavity Fabry-Perot (FP) optical filter. Voltage

This thesis examines the role of photonics and integrated optics (IO) for use in analog-to-digital conversion in electronic warfare (EW) intercept receivers. The IO approach uses a continuous wave (CW) distributed feedback (DFB) laser diode at a peak wavelength of 1550 nm to oversample two Mach-Zehnder interferometers (MZIs).

DESIGN OF HIGH-SPEED CMOS LASER DRIVER USING A

In this thesis, a computer simulation has been done to evaluate the wavelength chirping and pulse broadening effects induced by the direct intensity modulation using Distributed Feedback (DFB) laser diodes. In the simulation, a DFB laser diode is driven by either square wave current pulses or pulses with a small current Step in the
