High power short pulse generation at high repetition rate from InGaN violet laser diodes

The generation of 22 ps pulses with peak powers of 0.74 W by a gain-switched InGaN violet laser diode is reported. Significant pulse width dependence on repetition rate is observed. © 2011 OSA.

Simultaneous pulse compression and jitter reduction at 10GHz using novel self-seeding gain-switched DFB laser incorporating a DILM

A novel scheme using a 10 GHz gain-switched DFB laser with simultaneous pulse width and jitter compression allows generation of 380fs pulses with both system limited 150fs jitter and 30 dB extinction ratio. ©1999 Optical Society of America.

Demonstration of multi wavelength picosecond pulse generation with resonant RF drive using an monolithically integrated multi-grating cavity (MGC) laser

Multiwavelength pulses were generated using a monolithically integrated device. The device used is an integrated InGaAs/InGaAsP/InP multi-wavelength laser fabricated by selective area regrowth. The device self pulsated on all of the four wavelength channels. 48 ps pulses were obtained which were measured by a 50GHz oscilloscope and 32GHz photodiode which was not bandwidth limited. Simultaneous multi-wavelength pulse generation was also achieved.

1 × 4 space switching and simultaneous all-optical wavelength conversion at 2.488Gbit/s using a single monolithically integrated multiwavelength laser

A novel InGaAs/InGaAsP/InP integrated multiwavelength grating cavity laser is presented, which has been used to demonstrate space switching and simultaneous all-optical wavelength conversion at bit rates of 2.488 Gbit/s. This has been achieved using a single monolithically integrated device without the need for post-filtering to separate the converted signal from the input.

Gaussian etched single transverse mode vertical-cavity surface-emitting laser

A continuous Gaussian profile matched to the fundamental mode was etched onto the aperture of a vertical cavity surface emitting laser (VCSEL). Single Gaussian spot emission was achieved over the entire operating current range.
