Balanced Opticalto Microwave
Phase Detector(BOM-PD)
The Balanced Optical Microwave PhaseDetector (BOM-PD) is a high resolution
stand-alone external phase detector
engineered for ultra-low noise detection of the phase between optical andRF signals. Due to its improved balanced Sagnac-interferometer technology this device is intrinsically low drifting
while having large detection sensitivity.
The BOM-PD does not only allow anoutstanding synchronization of a laser
source to a custom reference frequency, it can also be used to synchronize
a low noise voltage controlled oscillator (VCO) to the laser source for a radio
frequency synthesis.
