This paper describes a new, compact, waveguide thermal isolator . The isolator is based on a recently developed microwave bandgap joint, a periodic structure which suppresses microwave fields propagating between two parallel conducting surfaces. When such a

Analysis of Temperature Dependence of Ce: YIG for Athermal Waveguide Optical Isolator
free download

The temperature dependence of optical properties of magneto-optic garnet Ce: YIG was analyzed for the athermal operation of the Mach-Zehnder interferometer (MZI) optical isolator composed of an SOI-based waveguide with a Ce: YIG upper cladding layer. By A waveguide optical isolator with a nonreciprocal phase shift is promising for obtaining high optical isolation owing to its single-polarization operation. A typical configuration enables operation for only the TM mode input light. A silicon waveguide polarization rotator with

To eliminate one of the main noise sources in an optical telecom link, it is necessary to protect the lasers from optical feedback by including an optical isolator in the laser diode package. With todays commercial bulk isolators the packaging of a laser diode module

Optical Waveguide Isolator Based on Nonreciprocal Loss/Gain of Amplier
free download

The effect of nonreciprocal loss/gain of a waveguide optical amplier covered by an absorbing magnetooptic layer was studied for the rst time. It is shown that the optical losslgain of this amplier differs for the forward and backward propagation when the

A method based on Yehs rigorous 4 X 4 matrix algebra and a fast perturbation-theory-based method are posed for modeling and optimization of an integrated magneto-optical (MO) waveguide isolator . The trans. verse MO Kerr effect in ferromagnetic CoFen is used to

Magneto-optical waveguide isolator with 104 dB/cm non-reciprocal propagation
free download

Optical isolators protect active devices (ie lasers) from optical feedback. All research in the past focused on transmission of the light through ferromagnetic garnets with low optical loss at telecom wavelengths and strong magneto-optical (MO) Faraday effects. The
