An Integrated Resonantly-Coupled Dual-Wavelength Tunable External Cavity Laser is achieved using a common resonator and two or more independent resonators to select the two laser wavelengths. The resonators are present within the laser’s cavity, so no external frequency offset locking is required. The lasers are intrinsically frequency offset locked through the common resonator. The architecture achieves frequency offset locking by monitoring and controlling low-speed signals, greatly reducing the cost, size, weight, and power of comparable locking approaches. The laser provides broadband locking, because locking is achieved in the optical domain, without the need for high-frequency electronics. A 5-resonator architecture can enable finely resolved frequency offset tuning, as required for many RF downconverter applications using broadband reflective optical amplifiers.

A system for covert sensing and communications encodes a broadband light source using quantum entanglement-assisted waveform coding to spread a narrow-band signal over frequency. The light source generates broadband light and from that pairs of entangled photons that form a reference and a signal at different wavelengths.

A phase conjugator mixes the reference with the broadband light to shift the reference to the same wavelength as the signal and performs a phase conjugation to output a phase conjugated reference as a local oscillator. An optical delay time delays the local oscillator to approximately match a time-of flight delay to the target and back. Light reflected from the target is combined with the local oscillator, detected using direct detection heterodyne, homodyne or quasi-homodyne techniques, demodulated and decoded to recover the narrow-band signal and estimate the phase of the reflected light relative to the transmitted light to provide fine range estimates for the target and a covert communications channel.
