“…These waveguides have attracted substantial interest since their initial analysis [9]. Their interesting birefringence properties [10,11] were utilized to produce devices such as polarization splitters/combiners [12] while their versatile waveguiding properties were used to tailor the profile of their guided modes [13]. BRWs are also attractive for nonlinear propagation, where spatial optical solitons have been studied [14], and nonlinear optical modes have been found to propagate at higher optical powers in waveguides that have no bound modes in the linear regime [15].…”

A novel design to achieve phase matching between modes of a vertical distributed Bragg reflector waveguide and those of a conventional total internal reflection waveguide is reported for the first time. The device design and structure lend themselves to monolithic integration with active devices using well developed photonic fabrication technologies. Due to the lack of any modulation of the optical properties in the direction of propagation, the device promises very low insertion loss. This property together with the large overlap integral between the interacting fields dramatically enhances the conversion efficiency. The phase matching bandwidth, tunability and dimensions of these structures make them excellent contenders to harness optical nonlinearities in compact, low insertion loss monolithically integrable devices.

“…BRWs have several guiding properties that depart from what is expected from conventional TIR waveguides, which has attracted significant interest [82]. Their unique birefringence properties [83,84] have been utilized to produce novel devices such as polarization splitters/combiners [85], while their versatile waveguiding properties have been used to tailor the spatial profile of their guided modes [86,87].

Techniques used to assist phase matching of second-order nonlinearities in semiconductor waveguides are reviewed. The salient points of each method are highlighted, with their strengths and weaknesses with regard to various key applications discussed. Recent progress in these techniques is also reviewed. Emphasis is placed on two techniques, namely quasi-phase matching via domain disordering utilizing quantum well intermixing, and exact phase matching using Bragg reflection waveguides.The figure shows (a) An optical microscope image of an ion implantation mask used to fabricate gratings used for quasiphase matching, (b) a scanning electron micrograph of an ion implantation mask, (c) a scanning electron micrograph of a semiconductor ridge waveguide structure, and (d) an optical microscope image of group monolithic ring lasers designed for integration with quasiphase matched structures.

“…Inspired by Bragg reflection waveguides [16][17][18][19] or transverse Bragg waveguides [20], a novel bandpass DWF is formed by symmetrically placing transverse Bragg stacks about a dielectric waveguide. This filter is named DWF based on transverse Bragg reflection (TBR).…”

We demonstrate that transverse Bragg stacks symmetrically placed about a dielectric waveguide can effectively filter a fundamental mode in the dielectric waveguide. A narrow bandpass dielectric waveguide filter based on transverse Bragg reflection is proposed and investigated numerically. The results calculated indicate that for the filter with Bragg stacks of longitudinal length 3.86 μm, there is high transmission (≥95%) in the wavelength range of 1294-1326 nm, whereas there is loss as high as 93.4% at 1550 nm. Owing to its simple and compact structure, this filter is expected to be applied to highly dense photonic integrated circuits.
