ABSTRACT:
High power, low degree of polarization superluminescent diodes (SLDS) are described. A semiconductor optical amplifier (SOA) which amplifies light in substantially one polarizaton state can be used to create a SLD by combining the output from both sides of this polarization sensitive SOA in a manner which results in a depolarized output.
