Patent ID: 7489440

Claim:
An optical transmitter package device comprising: a laser diode; an offset semiconductor optical amplifier operatively connected to said laser diode; a multimode fiber connected to said semiconductor optical amplifier; and a feedback circuit comprising an optical splitter connected to said semiconductor optical amplifier, wherein said semiconductor optical amplifier is offset a controlled amount from a center point of said laser diode such that a predetermined amount of optical output of said laser diode is coupled into said multimode fiber, wherein said semiconductor optical amplifier is offset relative to the direction of propagation of said optical output, wherein said semiconductor optical amplifier is adapted to operate in a frequency domain such that said semiconductor optical amplifier filters and spectrally reshapes optical output from said laser diode, and wherein said feedback circuit is adapted to sample reshaped optical output from said semiconductor optical amplifier and dynamically adjust at least one of said semiconductor optical amplifier and said laser diode.
