Method for temperature compensating an optical filter |
摘要 |
A method for temperature compensating an optical filter utilizes information relating to the temperature coefficient/constant of the optical filter to identify a value for the feedback resistor in a transimpedance preamplifier contained in a laser control system. Changes or effects in transmission resulting from temperature changes in the optical filter can be compensated by selecting a feedback resistor or resistors having a temperature dependence value and corresponding sign and magnitude to offset the undesirable effects on the transmission resulting from temperature tuning of a laser and thereby varying the temperature dependencies of the optical filter in the signal path.
