Feature
Widely Tunable Vertical Coupler Filtered Laser
Fortunately, continued advances in photonic integration technology have made possible the fabrication of novel wavelength filters, such as the grating assisted vertical coupler, that are inherently more broadly tunable than Bragg reflectors. By further employing advanced photonic circuit fabrication techniques, this filter has been integrated with a gain section to build a monolithic laser with a tuning range exceeding 500 Å.
