Abstract

A tunable Bragg reflector based on a 3D hollow waveguide (HWG) has been proposed. Ultrawide tuning ranges of 152 nm and 164 nm , respectively, in Bragg wavelengths of TE and TM modes of the Bragg reflector have been presented experimentally. With a 3D hat-shaped HWG, a giant birefringence of 0.012 has been demonstrated that can be varied with a variable air core to realize tunable polarization-manipulating devices. The ultrawide tuning in Bragg wavelength can be utilized to make a number of widely tunable photonic devices based on the proposed 3D HWG Bragg reflector.
