Patent number: 8625189Abstract: A sample of nonlinear optical material for use in a nonlinear optical device contains a grating comprising alternating regions of inverted and non-inverted nonlinear coefficient of the material, with the regions separated by boundaries positioned such that the grating can provide quasi-phase matching of a selected nonlinear optical interaction, and compensate for phase mismatch arising from the Gouy phase shift of one or more focused optical beams involved in the interaction. The boundary positions can be calculated for second harmonic generation or optical parametric generation and oscillation.Type: GrantFiled: January 16, 2009Date of Patent: January 7, 2014Assignee: University of SouthamptonInventors: Corin Barry Edmund Gawith, Peter George Robin Smith, Huw Edward Major

Method of fabricating waveguide devices which use evanescent coupling between waveguides and grooves
Patent number: 8538207Abstract: An optical waveguide device (10) comprises a planar substrate with a lower cladding layer (14), a core layer (16) and an upper cladding layer (18), a groove (20) in the substrate that extends at least into the core layer (16), and a waveguiding channel (22) in the core layer (16), wherein at least a part of the waveguiding channel (22), which may contain a Bragg grating, is sufficiently proximate to the groove (20) in the plane of the substrate for an evanescent field of light propagating in the waveguiding channel (22) to extend laterally into the groove (20). Material contained in the groove modifies the properties of the waveguiding channel, so that a sample of material can be analysed or an active material can be used to modulate the propagating light. The groove (20) can be made before the waveguide (22). The groove (20) can be made by cutting into the substrate with a saw and the waveguide (22) can be made by direct writing in the core layer (16) with an ultraviolet beam.Type: GrantFiled: March 20, 2008Date of Patent: September 17, 2013Assignee: University of SouthamptonInventors: James Christopher Gates, Corin Barry Edmund Gawith, Peter George Robin Smith -
