Modulation Bandwidth Enhancement of Monolithically Integrated Mutually Coupled Distributed Feedback Laser

Monolithically-integrated distributed feedback laser compatible with CMOS processing.

An optically-pumped, integrated distributed feedback laser is demonstrated using a CMOS compatible process, where a record-low-temperature deposited gain medium enables integration with active devices such as modulators and detectors. A pump threshold of 24.9 mW and a slope efficiency of 1.3 % is demonstrated at the lasing wavelength of 1552.98 nm. The rare-earth-doped aluminum oxide, used as t...

Experimental demonstration of modulation bandwidth enhancement in distributed feedback lasers with e - Electronics Letters

The inductance L of the laser discharge shows an abrupt high peak which is attributed to the temporary plasma constriction [4]. This is due to the attractive electromagnetic forces (Laplace force) because of the parallel motion of the electrons. The following expansion of the plasma is caused by the finite time required for the electric field to penetrate into the plasma. This is due to the wel...

DFB laser monolithically integrated with amplifier array

Record bandwidth and sub-picosecond pulses from a monolithically integrated mode-locked quantum well ring laser.

In this paper, we present the detailed characterization of a semiconductor ring passively mode-locked laser with a 20 GHz repetition rate that was realized as an indium phosphide based photonic integrated circuit (PIC). Various dynamical regimes as a function of operating conditions were explored in the spectral and time domain. A record bandwidth of the optical coherent comb from a quantum wel...
