Temperature compensated dynamic optical tag modulator system and method

摘要: A dynamic optical tag system and method that allows for operation over a wide temperature range. variable wavelength source, such as dual fiber laser, is generated by combining the outputs from two distributed feedback lasers having separate operating wavelengths using division multiplexer (WDM). quantum well modulator mounted on front surface of retro-reflector in remote receiver end communication link biased to modulate one laser wavelengths. At higher temperatures, can be operate at lasers. lower temperature, second The DC bias required tune reduced depending temperature.
