Abstract
The optical isolators used to protect semiconductor lasers
against optical feedback cannot be integrated. Therefore
we propose to fabricate a laser that has a strongly reduced
sensitivity to feedback. Simulations show that such a device
can be realized by employing a ring laser in which the
clockwise and counterclockwise modes are not coupled. To
achieve unidirectional lasing, this work proposes to use an
intra cavity weak optical isolator based on two phase modulators
that are driven 90 degrees out of phase. Simulations
show up to 3% of intensity feedback can be tolerated without
any distinguishable effect on the laser light.
