We investigate the selective amplification and filtering of injection-locked slotted Fabry-Perot semiconductor lasers. Current and temperature tuning are used to selectively filter and amplify subcarriers of coherent optical combs with a selectivity of at least 10 GHz with an optical gain of up to 18 dB for filtered lines. A side mode suppression ratio in(More)
Slotted Fabry-Perot (SFP) semiconductor laser diodes provide single mode operation [1], which is useful in various telecommunications applications. Under optical injection locking these lasers can be used in the production of single mode coherent combs. These combs have potential application in Coherent Wavelength Division Multiplexing (CoWDM) [2]. They are(More)
