This technology is a laser cavity design that uses an integrated resonator as a cavity mirror for on-chip lasers.
While optical networks are moving towards integrated, chip-based solutions to address the size, power, and cost of optical transceivers, existing silicon-based lasers either have linewidths that are too broad to meet application requirements or possess high losses and overly complex designs, leading to large footprints and increased costs. Thus, there is a need for low-loss, integrated lasers with narrow linewidths that reduce design complexity, footprint, and cost.
The technology comprises only a silicon nitride resonator and a gain chip, leading to reductions in size, complexity, and cost. In contrast to related technologies, the tunable, low-loss resonator acts collectively as an output mirror, filter, and propagation delay, thereby eliminating the need for additional components. Furthermore, this technology facilitates a sub-millimeter silicon nitride laser cavity with narrow linewidth.
A prototype of the technology was demonstrated to have a 13-kilohertz linewidth, 1.7-milliwatt output power, and 27-nanometer wavelength range at 1550 nanometers.
