Abstract: The invention relates to the fabrication of optical switches in transparent substrates. The method includes exposing part of the substrate to a stream of femtosecond laser pulses to form an exposed volume which can later be etched to form a channel used for microfluidic control of the switch. This process is referred to as femtosecond laser induced chemical etching (FLICE). The waveguides of the optical switch are also written in the substrate by using femtosecond laser inscription (FLI), which can be performed in the same operation as the exposure step in the FLICE formation of the channel, thus ensuring alignment between the waveguides and the channel.

Abstract: 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.
