Established in May 10, 2000, OPTOWELL Co., Ltd. is a venture-backed, pre-public company with a growing workforce and an existing production capacity. OPTOWELL's technological team headed by Dr. Gye Mo Yang has researched relentlessly uring the last 15 years and now, to develop key technologies for crystal growth and device manufacturing process We supply GaAs-based VCSEL, GaAs PIN PD, RCLED & UHB LED?s wafer, Chip & Package with high quality.
OPTOWELL has offered GaAs-based VCSEL wafers (on 3" GaAs), suitable for oxidation or ion-lantation processes. The wafers can be used to create a range of arrays, e.g. 1x4 and 1x12 and 2-dimensional matrix devices with speeds up to 4.25 Gb/s for each device.We specialize in design, epitaxy, and manufacturing of the VCSELs, PDs, RCLEDs & UHB LEDs for electronic communication industries. OPTOWELL manufactures VCSELs, PDs, RCLEDs & UHB LEDs for supplying them to other package and transceiver venders who lack epitaxy and/or processing technologies Vertical Cavity Surface Emitting Lasers (VCSELs) are compound semiconductor microlaser diodes that emit light in a circular beam vertically from the surface of a  fabricated wafer, and offer significant advantages when compared to the edge-emitting lasers currently used in the majority of fiber optic communications devices.VCSELs have high performance and low cost advantages.
   The key features are.
Simpler fabrication compared to edge-emitting lasers.Manufacturing cost saved by allowing on-wafer testing.Circular, low divergence output beams providing high coupling efficiency to optical fiber. Small active volumes leading to low threshold currents.High volume/high density production.Leading to ease of packaging.Leading to ease of 2D-Array.Optical Interconnects,     Optical Telecommunications,Optical Dacommunications,Gigabit Ethernet,Optical Switching .
