  • Packaging Assembly for High-Speed Vertical-Cavity Surface-Emitting Laser
    Publication number: 20190081455
    Abstract: A packaging assembly for a high-speed vertical-cavity surface-emitting laser (VCSEL) mainly applies a lens assembly consisted of several prisms to split a laser beam emitted by a VCSEL element so as to guide a small portion of the laser beam back to a monitor photodiode (MPD) and the rest of the laser beam to travel away along an optical axis. Such a spectacular design of the lens assembly can not only relieve the VCSEL element from a position right under the optical axis, but can also reduce signal loss by shorting a length of a bonding wire for a corresponding pin through disposing the VCSEL element further close to the corresponding pin. Thereupon, a defect of lights reflected from a lens or a translucent plate on a cap can be substantially improved.

    Abstract: An apparatus for performing a selenization and sulfurization process on a glass substrate is introduced. A low-cost, non-toxic selenization and sulfurization process is performed on a large-area glass substrate in a normal-pressure environment with the apparatus to turn element selenium or sulfur into small molecules of high activity at high temperature by pyrolysis or by plasma, especially linear atmospheric pressure plasma. The process is finalized by dispersing the selenium or sulfur molecules uniformly and allowing the glass substrate to undergo reciprocating motion precisely, thereby achieving large-area, uniform selenization and sulfurization of the one-piece glass substrate.
