VCSEL having polarization control and method of making same |
摘要 |
A vertical cavity surface emitting laser with polarization control includes a first stack of distributed Bragg reflectors positioned on a substrate with an active region including a first cladding region and a second cladding region positioned on opposite sides of an active area overlying the first stack of distributed Bragg reflectors A second stack of distributed Bragg reflectors is positioned on the active region. The second stack has an ion implantation region formed to control and define a lasing threshold of the laser. The second stack further is formed into a ridge with the ridge being etched into the ion implantation region to form an elongated shape so as to polarize light emitted by the second stack of distributed Bragg reflectors
