Abstract
A method of generating an anti-reflection optical coating on a laser diode includes determining a preliminary design for the coating, fabricating the coating on a first laser diode using an in-situ optical monitoring technique and measuring the performance of the laser diode. The steps of modifying the anti-reflection coating on the laser diode and measuring the performance of the laser diode are repeated until a performance maximum is determined. Another anti-reflection coating is fabricated a second laser diode and the performance of the laser diode is measured. Again, the steps of modifying the anti-reflection coating on the laser diode and measuring the performance of the laser diode are repeated until another performance maximum is determined. The above steps are repeated with additional laser diodes, as necessary, until a global performance maximum is determined. The coating parameters for the anti-reflection coating corresponding to the global performance maximum are used as the final anti-reflection coating design.
