✦ Synopsis

Abstract

An all‐fiber ratiometric wavelength monitor for optical wavelength measurement is proposed and investigated theoretically as well as experimentally. Two edge filters with opposite slope spectral responses based on the singlemode‐multimode‐singlemode (SMS) fiber structures are developed. A ratiometric wavelength measurement system employing the developed SMS edge filters demonstrates a high discrimination range of 20.41 dB and a potential wavelength measurement resolution of 10 pm over a wavelength range from 1530 to 1560 nm. © 2008 Wiley Periodicals, Inc.

## Abstract A voltage sensor based on a singlemode–multimode–singlemode (SMS) fiber structure, attached to a piezoelectric (PZT), used in a ratiometric optical power measurement scheme is proposed. The elongation of the PZT due to an applied voltage induces a strain on the SMS fiber structure and i
