Latest Patents

Chui's latest patents include methods for forming index guided vertical cavity surface emitting lasers. The Planar Index Guided Vertical Cavity Surface Emitting Laser (PIG VCSEL) utilizes index guiding to enhance optical confinement and employs proton implantation to improve current confinement. This innovative design achieves index guiding by etching index guide openings around the optical confinement region, which can be adjusted by varying the etched volume of these openings. Additionally, the PIG VCSEL increases the top contact surface area, thereby lowering contact and device resistance, which further enhances VCSEL performance. The device is designed to be substantially planarized, facilitating ease of manufacture.
