A stabilised fiber-optic Mach-Zehnder interferometer for carrier-frequency rejection
نویسندگان
چکیده
We have demonstrated stabilisation of a fiber-optic Mach-Zehnder interferometer, with a centimetre-scale path difference, to the transmission minimum for the carrier wave of a frequency-modulated laser beam. A time-averaged extinction of 32 dB, limited by the bandwidth of the feedback, was maintained over several hours. The interferometer was used to remove the carrier wave from a 780 nm laser beam that had been phasemodulated at 2.7 GHz.

متن کاملInterferometric Fiber Optic Sensors
Fiber optic interferometers to sense various physical parameters including temperature, strain, pressure, and refractive index have been widely investigated. They can be categorized into four types: Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac. In this paper, each type of interferometric sensor is reviewed in terms of operating principles, fabrication methods, and application fields. Some s...
متن کاملSensitivity Enhancements to Photonic Electric Field Sensor
This paper describes an electrode-less, all-optical, wideband electric field sensor fabricated in an electro-optic lithium niobate substrate. The sensor component is an integrated optic Mach-Zehnder interferometer. The electric field sensor uses the electro-optic properties of lithium niobate to modulate the phase of the light propagating in each arm of the Mach-Zehnder interferometer. The phas...

Due to the increasing growth of processing cores in complex computational systems, all the connection converted bottleneck for all systems. With the protection of progressing and constructing complex photonic connection on chip, optical data transmission is the best choice for replacing with electrical interconnection for the reason of gathering connection with a high bandwidth and insertion lo...
متن کاملFabrication and characterization of Mach–Zehnder interferometer based on a hollow optical fiber filled with radial-aligned liquid crystal
We demonstrate a high sensitivity allfiber Mach–Zehnder interferometer (MZI) based on radialaligned liquid crystal (LC) in a hollow optical fiber (HOF). The transmission spectrum of the liquid crystalfilled fiber MZI (LCFMZI) was measured at different temperatures, and the thermalinduced wavelength shift of the interference spectrum probed. The experimental results indicate that the LC ali...
