Wavelength and power monitoring of DWDM systems using scanning F–P filter calibrated with a F–P laser
نویسندگان
چکیده
A novel technique to overcome the long-term drift and hysteresis of a scanning Fabry–Perot filter was developed and applied to wavelength and power monitoring of DWDM system. By using the comb peaks generated by a temperaturestabilized, near threshold-biased Fabry–Perot diode laser as wavelength reference for the scanning Fabry–Perot filter, wavelength and power measurement accuracy of better than 10 pm and 0.2 dB, respectively, were achieved. 2002 Elsevier Science B.V All rights reserved..

Design of the [SiO2/ZrO2] photonic crystal filter for application in 350-nm laser safety glasses
In this paper, a one-dimensional photonic crystal filter based on the [SiO2/ZrO2] bilayer have been designed for application in safety glasses for working in 350-nm wavelength. High power lasers with low wavelength e.g. 350-nm have very high power which can cause serious damage to the operator’s eyes. In this paper using the transfer matrix method and theoretical calculation in MATLAB software ...
