The Laser output power must be stable especially in safety reason. But the Laser power is related to the Junction Temperature (Tj) of the LD. It means that as the different Tj, the Laser power will be increased or decreased. An APC (automatic power control) circuit is used to compensate the varying Laser output power to constant. As shown in the picture, The principle of the APC circuit is monitoring portion of the laser light from the LD by the built-in PD and real-time feedback to control the laser output power constant and safety.

** Operation temperature means within this temperature range, the laser spot/line will not be affected to change the spot size/line width. It can still work over this range, but the laser spot size or laser line width will be larger.

Knowles DLI brand microstrip bandpass filters offer classical filter topologies yielding excellent performance in a small footprint when fabricated on ceramic substrate materials. Miniaturization can reach new levels by employing DLI high-k ceramic materials. Different techniques are employed to realize small size and high performance. Catalog devices come complete with integrated shielding and the surface mount versions are designed for use on most RF PWB materials. Typical features include center frequency from C to above Ka band although custom devices are avaliable from 1 to 60 GHz. Bandpass filters pass desired frequency range and suppress the rest of undesired spectrum. Designed from 800MHz to 67GHz.
