Description: Carrier-phase synchronization can be approached in a
general manner by estimating the multiplicative distortion (MD) to which
a baseband received signal in an RF or coherent optical transmission
system is subjected. This paper presents a unified modeling and
estimation of the MD in finite-alphabet digital communication systems. A
simple form of MD is the camer phase exp GO) which has to be estimated
and compensated for in a coherent receiver. A more general case with
fading must, however, allow for amplitude as well as phase variations of
the MD.
We assume a state-variable model for the MD and generally obtain a
nonlinear estimation problem with additional randomly-varying system
parameters such as received signal power, frequency offset, and Doppler
spread. An extended Kalman filter is then applied as a near-optimal
solution to the adaptive MD and channel parameter estimation problem.
Examples are given to show the use and some advantages of this scheme.

Description: calculate the band of Fabry-Parot Filter -A Fabry-Parot Filter consist of the cavity formed by two highly reflective mirrors placed parallel to each other , as shown in the figure 1.The input light beam to the filter enters the first mirror at right angles to its surface. The output of the filter is the light beam leaving the second mirror. This filter is called Fabry-Parot or etalon. This is a classical device that has been used widely in interferometric applications. Fabry-Parot filters have been used for WDM in several optical network test beds. There are better filters today, such as thin film resonant multi cavity filter and they can still be viewed as Fabry-Perot filter. This type of filter transmits a narrow band of wavelengths and rejects wavelengths outside of that band. An interesting feature of this type of filter is its ability to "select" a different peak wavelength as the filter is tilted

-We propose a novel approach to realizing all-optical
microwave filtering using an array of fiber Bragg gratings with
identical reflectivities. The filter tapping coefficients are determined
by the spectrum profile of a broadband light source and
the central wavelengths of the gratings. Since the fiber Bragg
gratings have identical reflectivities, the characteristics of the
gratings with high uniformity are possible, which simplifies the
fiber Bragg grating fabrication and reduces the implementation
error. In addition, the spectrum profile of the broadband light
source can be controlled using an optical filter, which could be used
to control the filter coefficients to suppress the filter sidelobes. A
microwave filter using four fiber Bragg gratings is experimentally
implemented.

-We designed and experimentally demonstrated a
Bragg grating-assisted wavelength-division-multiplexing filter for
the three-wavelength multiplexing on a planar-lightwave-circuit
platform. The 1310- and 1550-nm lights were designed to be
separated after passing the directional coupler by a half-cycle
and a full-cycle coupling actions with losses of 0.07 and 0.19 dB,
respectively. The 1492-nm light was reflected back by a Bragg
grating fabricated on the directional coupler and its loss was less
than 2.0 dB. We also introduced and discussed the new concept of
an integrated optical triplexer transceiver using this filter.
