AB  - In this research, a new cost effective wavelength shifter has been proposed. A frequency shifter is
demonstrated in this research to realize a shift of signals in the mm-wave region. Proposed technique provides
a single sideband signal without the carrier signal due to the stimulated Brillouin scattering in optical fiber.
Bandwidth efficiency of double sideband signals is less as compared to SSB-SC signal. The frequency shifter
is all optical due to the fact that it uses a optical fiber’s performance degrading issue such as SBS as a
application. This generation of enhanced carrier power and single sideband is dependent on the Brillouin
scattering and principle of gain and loss spectrum of SBS inside optical fiber is used to eliminate the up shifted
frequency component and enhance the low shifter frequency component. A single sideband is obtained from
SBS phenomenon which is useful in advance modulation formats and requires less bandwidth. It is noteworthy
that SSB-SC signal is realized using all optical method and proposed work eliminates the necessary of non
optical components such as 90° hybrid couplers. SSB-SC signals are well competent to combat with pulse
broadening issues and have potential to work in terahertz frequency. To validate the performance of generated
signal, transmission of SSB-SC signal is also presented. Moreover, SSB-SC, SSB with carrier, DSB-SC and DSB
with carrier signals are compared in terms of Q-factor at varied link lengths.
