摘要： A laser system and method for self-injection locking. The system includes a laser having a laser output at a frequency ωo. An optical port provides a portion of the laser output at the port and a modulator, coupled to the port, is driven by a RF signal at a frequency ωm generates two sidebands at ωo±ωm. A filter passes one of the two sidebands; and an optical path couples an output of the filter to the laser for injection locking.

摘要： An architecture that enables one to realize a FIR transversal filter with apodized, interlaced bipolar tap coefficients (an). The tap coefficients, an, are varied via the control of the optical powers emitted by an array of WDM laser sources. Also, a filter architecture where tap coefficients can be agilely reconfigured in both polarity and magnitude. One chirped fiber-grating may be used to implement a series of wavelength-dependent tap-weights. The filter designs can be utilized to eliminate the low-pass response centered at DC, allowing one to place the center frequency (fc)1 of the first passband at a targeted intermediate frequency (IF).

摘要： A laser transmitter with a feedback control loop for minimizing noise. The novel laser transmitter includes a laser, an external reflector adapted to form an extended cavity to the laser, and a feedback control loop adapted to detect noise in the laser and in accordance therewith, adjust the optical phase of the extended cavity such that the noise is at a desired level. The optical phase of the extended cavity is adjusted by adjusting an operating parameter of the laser, such as its bias current. In an illustrative embodiment, the feedback control loop is adapted to compute the rate of change of the noise with respect to bias current and in accordance therewith, adjust the bias current of the laser such that relative intensity noise and interferometric intermodulation distortion are simultaneously minimized.
