An optical device includes a unitary substrate of optically transparent material. The unitary substrate has formed therein at least one collection lens and channel, the channel for receiving an optical fibre and arranged to align the optical fibre inserted therein such that the collection lens couples light collected by the collection lens into the optical fibre.

A method of forming an optical interconnect between first and second photonic chips located on an optical printed circuit board (OPCB) includes applying a coupling agent to a bonding surface of a flexible, freestanding polymer waveguide array film having at least one polymer waveguide disposed therein. The waveguide array film is placed onto the first and second photonic chips so that the waveguide array film extends over a gap and/or a step between the first and second photonic chips to thereby form a bonding interface between the bonding surface of the waveguide array film and the first and second photonic chips. The coupling agent is selected such that optical coupling between the first and second photonic chips arises simultaneously with formation of the bonding interface.

The disclosure relates to multilayer polymeric matrix based medical devices. In one example, a device comprises an inner first polymeric matrix and an outer second polymeric matrix. The addition of second polymeric matrix modifies bulk properties of each matrix thus resulting in a device where specific bulk properties are incorporated. The disclosure also relates to methods of manufacturing various embodiments of medical devices and their uses.

A tapered core structure is written on the end of an optical fiber using a 3D-printing process. The tapered core may expand the mode diameter for improved coupling between fibers or may reduce the mode diameter to enhance coupling to a waveguide smaller than the fiber core. The written core is surrounded by a cladding. The diameter of the core is varied while it is being written, allowing a wide range of taper profiles to be implemented. The 3D-printing process is readily adapted to permit multiple fibers to have tapered cores written on their ends during the same process cycle.

Embodiments described herein relate to methods of fabricating waveguide structures with gratings having front angles less than about 45 and back angles less than about 45.
