            Abstract : 
A deep-ridge vertical-groove distributed feedback (DFB) waveguide has been fabricated. Structural birefringence of the fabricated device was completely eliminated by controlling waveguide width. Additionally, polarisation independence of the grating coupling coefficient was accomplished by adjusting grating depth
