N2  - Optical gates are the fundamental building units for the development of  photonic networks in which information is handled exclusively in the optical  domain without problematic optoelectronic conversions. In this thesis all optical  molecular logic gates (AND, XOR) are proposed and implemented using azo  dye doped polymer film (DR1 doped PMMA) based on holographic diffraction  grating. First, the linear polarization grating of the four dyes doped in polymer  DR167- PMMA, DR13-PMMA, MR-PMMA and DR1- PMMA films and their  response is discussed. In the proposed system, scaling down the setup size has  been realized by replacing gas lasers by semiconductor laser diode.  Consequently, the setup cost has been considerably reduced. We verified the  laws of diffraction and calculated the number of lines per mm. We used a red  beam from laser diode as a probe. The diffraction of the red beam is measured.  The effect of temperature on the diffraction grating is measured. We tested the  performance of the proposed gate with modulated input signal. Three types of  modulated signals are presented AM (amplitude modulation), FM (frequency  modulation), OOK (ON-OFF Keying) modulation
