ABSTRACT:
A vertical cavity surface-emitting laser package comprising: a first lead frame and a second lead frame, wherein the signal is inputted from the first lead frame and connected to ground through the second lead frame, and the two lead frames are approximately parallel to each other; a vertical cavity surface-emitting laser diode, disposed above the front portion of the first lead frame and connected to the front portion of the second lead frame via a bonding wire; and epoxy resin packing the space around the front portions of the first and second lead frames, the vertical cavity surface-emitting laser diode, and the bonding wire for fixing and protecting them from damages. Besides, the optical fiber can be connected to interior of the package via top surface of the epoxy resin to guide signals in or out; or grating is utilized to reflect the light emitted from the vertical cavity surface-emitting laser diode, and a light detector is utilized to receive the reflected light such that automatic power control can be performed according to the reflected light received.
