Abstract :
The authors present the first longitudinally distributed bandgap source which can be used as a broad spectrum (80 nm FWHM) LED or a broad spectrum (11 nm FWHM) laser centred at 1.53 μm. The device was fabricated with low pressure MOVPE using selective area epitaxy. A multiple electrode design allows a flat topped output spectrum. Used as an LED, the authors couple -4.5 dBm into a lensed singlemode fibre; as a laser they couple 3 dBm. They also observe amplitude self pulsing of the source at 68 MHz slightly above laser threshold
