摘要： A tunable transmission optical filter is optically coupled between a laser section and semiconductor optical amplifier (SOA) section of a tunable laser device. The optical filter may be tuned to provide a high transmission near the lasing peak while suppressing a significant portion of back-propagating amplified spontaneous emission (ASE) of the SOA section. Without the optical filter, the laser output spectrum may develop side lobes of higher intensity after the ASE is amplified and reflected in the forward direction by the laser gain and mirror sections. While lessening the side lobes, the optical filter simultaneously transmits the laser peak for amplification by the SOA section.

摘要： A wavelength-division lightwave multiplexing device, and method of its manufacture, having an embedded filter and two parabola-shaped crossing waveguides, the waveguides providing collimation of light transmitted therein. At least one of the parabola-shaped wave crossing waveguides includes a first port, and a second port, and a widened portion between the first and second ports having a parabola-shaped profile, wherein the widened portion widens from the first port toward a midpoint thereof, and then narrows to the second port. The invention achieves low insertion loss and high spectral isolation while keeping a narrow guard band smaller, and addresses the problem of poor spectral isolation characteristics in the filter-embedded waveguide WDM device when it is adopted to applications requiring a guard band narrower.
