Technical content

The CHPDV21x0R is an advanced waveguide photodetector chip integrated with a Bias-Tee. The High-Power Photodiode utilizes a mode-converting tapered waveguide for efficient fiber-to-chip coupling and a 1×4 Multi-Mode Interference (MMI) Coupler. The optical signal is split by the MMI coupler into 4 equal parts and then it is fed into an array of 4 photodiodes which are connected in-parallel. It has a responsivity of 0.5 A/W at 1550 nm and a high saturation photocurrent of 30 mA at 20 GHz. The CHPDV21x0R can deliver 4.5 dBm RF output power at 20 GHz and 1.5 dBm at 50 GHz. The device exhibits a high linearity with typical OIP3 values above 20 dBm at a frequency of 40 GHz. FEATURES APPLICATIONS
