Global Communication Semiconductors, Inc. (GCS) Announces Breakthrough in InP based PIN Detectors
GCS, meets performance requirements for 1310 and 1550 PIN detectors utilized in 10G telecommunications applications.
Torrance, CA. GCS, Inc. (Global Communications Semiconductor, Inc.) a leading pure-play III-V compound semiconductor foundry service provider, announced that the company had reached a major milestone in the development of its 4"-wafer InGaAs mesa PIN photodiode process for 1310 nm and 1550 nm high-speed optical fiber communication applications.
"Conventional planar InP-based photodiode process with Zn-diffused p-contact typically deals with small size wafers of 2-inches (50mm) in diameter, and is limited in speed performance due to inherent parasitic capacitance." remarked Dr. Samuel C. Wang, Vice President of Optoelectronics, "GCS mesa approach offers advantages of large wafer size (4-inches, 100mm) processing as well as higher speed performance. The breakthrough came as successful passivation of the exposed small-bandgap intrinsic layer in the device s mesa structure. The diode s responsivity exceeds 0.9 A/W at 1310 nm, while the -3dB bandwidth hits 19 and 23 GHz for 24- and 18-micron diameter diodes, respectively, measured with a 50 ohm input impedance TIA. continued Dr. Wang.
This new InGaAs PIN PD process represents an important addition to GCS portfolio of Optoelectronics production foundry services, such as GaAs PIN and MSM photodetectors, optical modulators, optical ridge waveguides and QWIP.
"We have taken a major step forward to answer the need for 10Gb/sec requirements by the manufacturers of telecommunications lasers. GCS InP based PIN diode foundry process yields dark current figures suitable for 10Gb/sec applications and beyond." commented Dr. Owen K. Wu, CEO and President of GCS. "This process breakthrough in optoelectronics coupled with GCS state-of-the-art InGaP and InP HBT technologies brings OEIC closer to reality," continued Dr. Wu.
Global Communication Semiconductors Inc., based in Torrance, California, an ISO 9002 certified company, provides compound semiconductor foundry services to the wireless telecommunication and high-speed networking industries. GCS currently offers foundry service for both InGaP and InP HBT
processes and provides optoelectronic foundry services for PIN diodes used in the fiber optic communication market.
