Abstract:
A photonic integrated circuit (PIC) includes a semiconductor substrate with a main bus waveguide disposed within the substrate. Two or more ring lasers are disposed within the substrate and are optically coupled to the main bus waveguide. The ring lasers have a wavelength control mechanism allowing change of a lasers emitted wavelength. A wavelength selective filter is optically coupled to the bus waveguide. A control circuit is electronically coupled to each wavelength control mechanism, and the wavelength selective filter. The control circuit in conjunction with the selective filter allows monitoring of a ring laser's wavelength on the main bus waveguide. Based on a determined wavelength, the control circuit may change a ring laser wavelength to a desired wavelength to achieve a desired wavelength spacing for each of the ring lasers. The PIC may be integrated as a coarse wave-length division multiplexing (CWDM) transmit module.

Claim (Index 17):
A method for tuning a photonic integrated circuit, the method comprising:\n transmitting a first wavelength emission through a bus waveguide using a first ring laser; receiving a portion of the wavelength emission using a wavelength selective filter; determining a first photocurrent value for the first wavelength emission; transmitting a second wavelength emission through the bus waveguide using a second ring laser; receiving a portion of the second wavelength emission using the wavelength selective filter; determining a second photo current value for the second wavelength emission; generating a map of each laser's wavelength of resonance as a function of the bias on the wavelength selective filter and the determined photocurrent values; determining whether each laser's wavelength aligns with a channel spacing grid; and adjusting the wavelength of the first ring laser, and the second ring laser, to align the wavelengths to the channel spacing grid.
