摘要： The invention comprises a Schottky barrier type infrared photodetector which is monolithically integrated on a silicon waveguide. A Schottky barrier contact is positioned directly on a silicon waveguide to absorb grazing incidence optical signals passing through the waveguide. The Schottky contact is operated in the avalanche or reverse bias mode to generate a useable electrical signal.

摘要： All silicon electrooptic devices for modulating and switching of guided light have been developed using the silicon-on-insulator approach. Generally, p-n junctions are formed in a silicon waveguide to selectively modulate and direct light by carrier refraction. An electrooptic phase modulator and several 2.times.2 electrooptic switches are described. The devices are particularly useful for manipulating light signals in the 1.3-1.6 micron range.

摘要： The 2.times.2 bypass switch utilizes a single polarizing beam splitter and a 90.degree. polarization twist layer of liquid crystal held between two right angle prisms. The outer surfaces of the prisms provide a series of total internal reflections to direct light about the switch so that a single polarizing beam splitter may be employed to divide an incident beam into two counter-rotating orthogonally polarized beams and to recombine the beam at the switch selective output port. A compound switch is realized by double folding the optical path in two parallel planes in one embodiment and along parallel paths in the incident plane in another embodiment.

摘要： A low crosstalk optical switching matrix of individual optical switches wherein anyone of n input ports may be addressed to any one of n output ports. Ports of the individual optical switches which are employed for inter-row and inter-column coupling at the interior of the matrix are not used in the last row and column and are terminated with optical signal absorbers thereat, thus providing a means for absorbing non-addressed signals and spurious reflections. The crosstalk properties of the matrix are further improved by utilizing a multiplicity of four port switching elements in tandem for each individual optical switch.

摘要： An optical signal low energy method for coupling electrical signals on-chip between component circuits of for example a CMOS circuit array. The described coupling method employs infrared signals communicated along a nano-scale resonant semiconductor waveguide between for example PIN diode signal transducers. The coupling may employ an electrically pumped laser, an electro absorption modulator and a photodetector all for typically the 1.5 to 2.0 micrometer spectral region with each formed using for example PIN heterodiode semiconductor devices. Each of these three devices includes active semiconductor crystal material situated in a resonator within a strip waveguide. The resonator is defined by two fabricated mirrors having a tapered location one dimensional photonic crystal lattice of oxide hole or slot apertures. Each semiconductor device is for example a heterodiode pumped or controlled by laterally disposed wings enclosing the resonator to form a lateral PIN structure for current injection or high E-field generation. CMOS compatible ten gigabit per second signals of low energy use per transmitted bit are achieved.

摘要： An electro-optical switch implemented in coupled photonic crystal waveguides is disclosed. The switch is proposed and analyzed using both a finite-difference time-domain (“FDTD”) method and a plane wave expansion (“PWM) method. The switch may be implemented in a square lattice of silicon posts in air, as well as in a hexagonal lattice of air holes in a silicon slab. Switching occurs due to a change in the conductance in the coupling region between the photonic crystal waveguides, which modulates the coupling coefficient and eventually causes switching. Conductance may be induced electrically by carrier injection or optically by electron-hole pair generation. The electro-optical switch has low insertion loss and optical crosstalk in both the cross and bar switching states.
