Abstract A new type all optical vibration and acceleration sensor using the combination of micromachined Si cantilever and optical fiber is proposed, and its fundamental characteristics are demonstrated. The light emitted from bulb-lens set into the V-groove is reflected at the reflector formed on the Si cantilever and then recoupled into the bulb-lens. Several sensors with different length (0.64–6.0 mm long) of the Si cantilever are fabricated to compare the theoretical resonance frequency fr obtained from the simple model and experimental ones. They had good agreement. From the sensing principle the sensing frequency range of the vibration is suitable below the fr of the Si cantilever of the sensor.

We provide a very general review of the resonant transmission line method for optical fiber problems. The method has been found to work seamlessly for a variety of difficult problems including elliptical and eccentric core fibers as well as “holey” photonic crystal fibers. This new version has been shown to offer great versatility with respect to cases of unconventional, inhomogeneous index profiles.

Optical Fiber Gratings

Nowadays, as a new type of optical fiber devices, with flexible structure characteristic and steady frequency-selecting performance among the key support device areas of optic fiber technology, Fiber Bragg Grating (FBG) is rapidly developed as an very important basic device.Therefore, the study of phase mask plate which will be good for the mass production of the optical fiber gratings is becoming a central issue. The appearance of phase mask plate technology makes the industrialized production of fiber optical gratings with a stable wavelength possible. This paper based on the optical fiber gratings written online is mainly about the study of related servo control system. By the design of the servo control system of phase mask plate, we will get the ideal purposes that phase mask plate is precisely positioned, torque of plate is increased and the time of picking any plate is undifferentiated.
