چکیده

A monolithically integrated tunable laser and quantum-well phase modulator is demonstrated. Phase efficiency under forward bias is improved >20dB at low frequencies compared with reverse bias. Bandwidths >30 GHz are demonstrated in frequency modulation measurements. 2006 Optical Society of America OCIS codes: (230 4110) Modulators; (230 5590) Quantum Well Devices This research was supported by DARPA under the PHOR-FRONT Program.

Design of a new asymmetric waveguide in InP-Based multi-quantum well laser

Today, electron leakage in InP-based separate confinement laser diode has a serious effect on device performance. Control of electron leakage current is the aim of many studies in semiconductor laser industry. In this study, for the first time, a new asymmetric waveguide structure with n-interlayer for a 1.325 μm InP-based laser diode with InGaAsP multi-quantum well is proposed and theoreticall...

Microwave generation in an electro-absorption modulator integrated with a DFB laser subject to optical injection.

This paper presents a new technique to generate microwave signal using an electro-absorption modulator (EAM) integrated with a distributed feedback (DFB) laser subject to optical injection. Experiments show that the frequency of the generated microwave can be tuned by changing the wavelength of the external laser or adjusting the bias voltage of the EAM. The frequency response of the EAM is stu...
