cladding without structural complexity having very high birefringent of the order of 10− 2,
less effective area of few square microns as well as low confinement loss of the order of 10−
2 dB/m at 1.55 μm wavelength. The zero dispersion wavelength is also achieved in the near
infrared region. This study clearly attributes to the fact that the zero dispersion wavelength at
the near infrared region, very high birefringence and low confinement loss can be adjusted …
