Abstract: (2783 Views)
In this paper bragg grating writing required for integrated lasers on single mode channel LiNbO3:Ti:Fe waveguide at 1550nm using a two beam setup has been demonstrated and it has been simultaneously shown on an optical spectrum analyzer(OSA ) how 1550nm wavelength from a broadband ASE source is being filtered with a linewidth of about 0.2 nm. The observed wavelength shift might be due to uncertainty about the exact value of the effective refractive index in waveguide and the mechanical errors of the two beam interference configuration while bragg grating writing.
