Broadband Detectors
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

C+L Band Broadband Light Source
S-103
ASE broadband source slot module of FOTS system can offer special function that is able to change optical output spectral feature variously, which is change optical output spectral feature variously, which is followed by user’s driving embedded pump LD freely. The output power of each pump LD is controlled separately by the program that is set up by user. In the case optimum ASE source output features such as wide broadband (> 80 nm @ -10 dBm/nm) and stable output power (< 0.02 dB) is needed, it is made up so that the provided Default mode along with User mode can be chosen and set up. More stable application of ASE source is possible through the combination of monitoring of ASE output power, alarm status and pump LD status with real-time optimal feedback. The embedded FPGA processor makes high speed control possible and enables monitoring and feedback routine operated stably.
