Optical device packages containing an optical transmitter die
First Claim
1. An optical device comprising:
- an optical transmitter die operating in an operational temperature for emitting light having characteristic light waves, the optical transmitter die comprising an automatic power control circuitry coupled to a vertical-cavity surface-emitting laser (VCSEL), the circuitry controlling operational power of the VCSEL to prevent the operational power from exceeding a threshold power limit; and
a package comprising mold material which encapsulates the optical transmitter die, wherein the mold material is clear to at least one of the characteristic wavelengths.

Abstract
An optical device package (18) includes an optical transmitter die (10) encapsulated within mold material (20). The mold material (20) allows light emitted from the optical transmitter (10) to pass through the package (18) and can have a lens pattern (22) molded therein to focus the light emitted from the optical transmitter. The mold material (20) can also have coupling patterns (32) formed therein to allow a supplemental lens assembly (28) to be coupled thereto so that supplemental lens patterns (30) formed in the supplemental lens assembly (28) can focus the light emitted from the optical transmitter (10). The optical device package (18) can also include an optical receiver (40) enclosed within the mold material (20) and mounted on a substrate (42) with the optical transmitter (10) to provide a complete optical product in one package (18).
