Claim 14:
15. A photonic device, comprising:
a first waveguide having an input port configured to receive an optical signal comprising M sub-signals each having a respective wavelength, M being an integer greater than or equal to two;
a second waveguide;
M tunable closed-loop optical resonators coupled to the first waveguide and configured to receive a respective tuning signal,
M passive closed-loop delay elements, each the M passive closed-loop delay elements being coupled to a respective one of the M tunable closed-loop optical resonators and to the second waveguide, each of the M passive closed-loop delay elements and the second waveguide being configured to couple at least 95% of an optical signal propagating in any of the M passive closed-loop delay elements to the second waveguide.
