Dynamic characteristics of long-wavelength quantum dot vertical-cavity surface-emitting lasers with light injection

Dynamic characteristics of long-wavelength quantum dot vertical-cavity surface-emitting lasers with light injection.

This investigation experimentally demonstrates the dynamic characteristics of quantum dot vertical-cavity surface-emitting lasers (QD VCSEL) without and with light injection. The QD VCSEL is fully doped structure on GaAs substrate and operates in the 1.3 mum optical communication wavelength. The eye diagram, frequency response, and intermodulation distortion are presented. We also demonstrate t...

1 . 3 l m quantum dot vertical - cavity surface - emitting laser with external light injection

Introduction: Quantum dots are attractive quantum structures owing to their superior characteristics and broad applications. A semiconductor laser with a quantum dot active region has been proven to exhibit excellent characteristics, including high differential gain, high modulation bandwidth, low threshold currents, and temperature insensitive threshold current density [1]. Quantum dot vertica...

Vertical Cavity Surface Emitting Lasers

The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping. Electrical pump has been less successful, but we have identified the proble...
