Abstract
An optical wavelength sweeping apparatus is disclosed. The optical wavelength sweeping apparatus includes a laser diode having an active region including a thickness of less than 1 μm, a cross-section of less than 7 μm, and a ratio of active region volume to total laser diode volume of less than 1/300, and a pulse generator coupled to the laser diode. The pulse generator is configured and operable to provide a current drive pulse to the laser diode to selectively and rapidly heat the active region and immediate vicinity to provide a peak increase in temperature of 30° C. or more at an end of the current pulse and to perform a wavelength sweep of emitted optical radiation which is greater than 5 nm. Methods of driving a laser diode and optical systems are disclosed, as are other aspects.
