Abstract

Planar Bragg grating based photonic Hilbert transformers are experimentally demonstrated in this work. Planar Bragg gratings are utilized to implement a general Hilbert transform, a fractional order Hilbert transform and terahertz bandwidth Hilbert transforms, using a direct UV grating writing technique in a silica-on-silicon platform. The design, fabrication and integration of the proposed devices are discussed and presented. The photonic Hilbert transformers could be further monolithically integrated with flat top reflectors and interferometric structures, implementing all-optical singlesideband filters
