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: Signal distribution arrangements are assembled by selecting a terminal body and a tap module combination that provides the desired signal strength at the intended position in an optical network. Each terminal body includes an input connection interface, a pass-through connection interface, a module connection interface, and multiple drop connection interfaces. Each tap module houses an optical tap having an asymmetric split ratio. Most of the optical signal power received at the signal distribution arrangement passes to the pass-through connection interface. A portion of the optical signal power is routed to the drop connection interfaces (e.g., via a symmetrical optical power splitter). The tap module and terminal body combination are selected based on the desired number of drop connection interfaces and to balance the asymmetric split ratio with the symmetric split ratio.

Abstract: An optical communications system includes a laser transmitter to generate an optical signal and a first optical fiber network coupled to transmit the optical signal from the laser transmitter system. A first latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal, and has a first tap output that receives a selected and alterable first fraction of the optical signal. A second latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal from the first latchable asymmetric coupler and has a second tap output that receives a selected and alterable second fraction of the optical signal incident at the second latchable. In certain embodiments the first and second couplers are capable of operating at any of at least three tapping fractions.

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.

Abstract: Optical devices a formed by mounting one optical chip directly to another. In some embodiments, one of the optical chips is formed in a low index contrast platform while the other is formed in a high index contrast platform. In other embodiments, one optical chip includes a number of optical functional elements having different operational characteristics, such as a number of optical taps having different tap ratios. A second chip is mounted to receive an optical signal from an optical functional element having a selected operational characteristic.

Abstract: An optical circuit that has a first input waveguide, at least a first output waveguide and an optical path between the first input waveguide and the at least a first output waveguide. A first totally internally reflecting (TIR) waveguide switch lies on the optical path between the first input waveguide and the at least a first output waveguide. A wavelength selective filter is disposed on the optical path between the first input waveguide and the at least one output waveguide, the wavelength selective filter being transmissive for light in a first wavelength range and reflective for light in a second wavelength range.

Abstract: An optical fiber ribbon cable is formed using thermally expandable core (TEC) fibers. Expanded optical cores are formed in sections of TEC fibers, so that each section of TEC fiber comprises a first region having an unexpanded core, a second region having an expanded core, and a tapered region between the first region and the second region. The respective sections are cleaved to length and formed into a ribbon. A hybrid optical fiber ribbon cable can be made by fusing single mode optical fibers of a single mode fiber ribbon cable with TEC fibers of a TEC fiber ribbon cable using a laser. The laser is also used to form tapered core regions in the TEC fibers to reduce coupling losses between the TEC fibers and the single mode fibers.
