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.
Polarization Maintaining, Large Mode Area (Pmvlma) Erbium-Doped Optical Fiber And Amplifier
The disclosed subject matter relates to a polarization-maintaining very large mode area (PM VLMA) Erbium-doped fiber and a polarization maintaining, Er-doped VLMA amplifier.
