Before And After

A wavelength tunable optical filter based on a fiber Bragg grating using piezoelectric bimorph is realized in this paper, and the tuning condition is theoretically and experimentally analyzed. The Bragg central wavelength of the filter can be easily tuned adopting to a DC voltage. The maximum strain of the central wavelength depends upon the maximum operating voltage, and the tuning range efficiency was as high as 1.2pm/V, the reflectivity, shape and the reflective spectrums of the fiber Bragg grating central wavelength almost keep unchanged before and after tunning. This paper provides a reference for optical fiber Bragg grating tuner.with high efficiency.

Output Characteristics

An integrated TOF (Tunable Optical Filter) based on thermo-optic effect in Silicon on insulator (SOI) rib waveguide is designed and simulated. The device is comprised of two high refractivity contrast Si/Air stacks, functioning as high reflectivity of DBRs and separated by a variable refractive index Si F-P cavity. The output characteristics are calculated and simulated based on Transfer Matrix Method (TMM). Wavelength tuning is achieved through thermal modulation of refractive variation of the cavity.As the cavity Si is heated,the refractive index of the cavity increases.When the temperature of cavity Si changes within100°C，the central wavelength gets a continuous 8nm shift from 1550nm to 1558nm, which is right located in the WDM (Wavelength division multiplexing) networks operating at C-band. Moreover, by calculating, the tuning sensitivity is about 0.08nm/°C. Owing to the compact size and excellent characteristics of integration, the proposed component has a promising utilization in spectroscopy and optical communication.

The Relationship

A fiber Bragg grating (FBG) temperature sensor with high pressure applied in down-hole is experimentally studied. The relationship between the central wavelength and the temperature and pressure of the fiber Bragg grating is derived. The experimental results show that the packaged FBG temperature sensor has improved linearity and good repeatability. Its linearity is more than 0.999. The good linearity of temperature and wavelength is also kept in the high pressure when the compression and decompression were carried out under the pressure of 0-20 MPa and temperatures of 0-100 °C. Besides, the structure is simple. It can be widely applied in down-hole and other occasions
