Paper Abstract

This experimental work presented in this paper investigates the quality improvement of pulsed diode laser Gain- Switched (GS) optical pulses. GS is a straightforward technique, however, these pulses exhibit long duration (10ps - 100ps), low power (in the mW range), are asymmetric and often come accompanied by pedestals or subpulses. Simultaneous compression and reshaping of these input low quality pulses has been observed experimentally for several input power values. These effects have been achieved using a Highly Nonlinear Optical Loop Mirror (HNOLM) designed to directly process these long duration complex pulses thus eliminating the requirement for pre-pulse conditioning. The NOLM is based on a Microstructured Optical Fiber and a Highly Nonlinear Semiconductor Optical Amplifier. This device is compact, and offers overall benefits in terms of reduced system complexity.
