We generalize the coupled-mode theory by treating the forward- and backward-propagating modes on the same footing via a generalized eigenvalue problem that is exactly equivalent to the waveguide Hamiltonian. The
The waveguide patterns are transferred to a SiO2 hard mask via reactive ion etching using CF4 and a-Si:H waveguides are formed using SF6. A 750-nm-thick SiO2 layer is deposited on the top of the waveguide core to isolate the guided mode from the integrated thin-film magnet to avoid ...

A directional coupler is a reciprocal network where in theory all ports are ideally matched and the circuit itself is theoretically lossless [7]. Directional couplers can be designed using microstrip, stripline, coax, or waveguide technology. The device itself comes in a variety of packages ranging...
The conditions for maximum isolation in a circulator may be derived from temporal coupled mode theory as, f1=f2κ1/√{square root over (3)},Qκ1=1, (4) where f1is the modulation frequency, f2the carrier frequency, Q is the quality factor of the resonator, and κ1is the couplin...

A non-reciprocal optical element, particularly for use as an isolator or circulator, and for connection to at least two monomode optical waveguides and which has a magneto-optical waveguide structure intended to be subjected to a transverse magnetic field directed perpendicularly to the direction...
By integration, a waveguide-based optical isolator can eliminate the need for large single crystals, magnets, polarizers, reciprocal rotators and prisms, and reduce the device footprint to the sub-millimeter range. Meanwhile, an integrated optical isolator solves packaging issues including lens ...
The designed isolator supports duplex operation mode in a 59 nm operating band, and the isolation rate is as high as −20 dB, while the whole size of the device is as small as 465 µm × 0.35 µm. 2. Non-Reciprocal Transmission in Saturated Gain Waveguide There is an important ...
