An integrated photodetector, the IPD-10, has been developed specifically for use in high-speed DWDM transmission systems. The tapped detector contains up to 10 channels and provides for real-time simultaneous monitoring of each channel. Optical properties include a broad wavelength range covering C and L bands, low back-reflection, and high photocurrent. The device contains a built-in tap coupler to enable power monitoring with a minimal loss of < 1.0 dB, uniform over the entire wavelength range. Other applications include monitoring power through optical amplifiers in DWDM systems.
