    Abstract: A laser diode module with a built-in high-frequency modulation IC used to remove the reflected noise generated as the laser beam reads the signal to be played back and directly packaged within a metal cap. The high-frequency modulation IC creates an electrical connection through wire bonding with several connection legs and the laser diode module. The packaged laser diode module has four connection legs. Two of these connection legs act as a positive and a negative terminal for supplying power to the built-in high-frequency modulation IC. The other two connection legs are electrically connected to an external automatic power control (APC) circuit and act as the positive terminal of the laser diode and the photo diode, respectively. In this way, the inconvenience of externally attaching a high-frequency current producing circuit board can be avoided, the productivity can be enhanced and the radiation of electromagnetic interference (EMI) can be reduced.

    Abstract: An adjustable optical signal delay module which adjusts power of an amplified spontaneous emission generated by a semiconductor optical amplifier and feeds the adjusted amplified spontaneous emission back to the semiconductor optical amplifier in a direction opposite to an optical signal being amplified by the semiconductor optical amplifier is provided. The feedback of the adjusted amplified spontaneous emission varies a group refractive index of the semiconductor optical amplifier and delays the transmission of an optical signal through the semiconductor optical amplifier. By that arrangement, the adjustable optical delay module obviates the need for the pump laser conventionally required by a coherent population oscillation mechanism. The feedback optical loop includes a variable optical attenuator, an optical filter, and optical circulators. A user can control the delay timing of optical signals via adjusting optical power in the feedback optical loop.
