Alan,

I wonder if you or others have any publications for the offset locking technique you used for your "Chroma-Matic" laser tuning work, other than the info on your website?

Your OPPL-based offset locking technique (using charge pump phase/Frequency detector) has many advantages over those using mixer phase detectors. Here at NASA Goddard we are developing wavelength locked laser transmitters targeting various missions such as LISA and ASCENDS. Thank you very much for sharing your technique on this website. we have learned a lot from it and would be glad to cite your technique in our future publications.

Best Regards,

Jeff
