Latest Patents

One of Macomber's latest patents is the high efficiency partial distributed feedback (p-DFB) laser. This innovative design features a second-order multi-mode p-DFB laser that boasts increased electrical-to-optical power conversion efficiency, stabilized wavelength, and narrowed emission linewidth. The laser incorporates an abbreviated grating housed within the laser cavity, strategically separated from both the front-end and back-end of the laser facets. Another notable patent involves cleaving laser diode bars that have gratings. This invention provides a wafer that is cleaved to create a facet for a Fabry-Perot cavity, equipped with Bragg gratings whose axes are offset by a small angle from the axis of the Fabry-Perot cavity. This design effectively mitigates the impact of the randomly uncontrollable location of the cleaved facet on the optical phase of the grating feedback.
