Experimental Verification of a Novel Integrated Optical Isolator Concept
نویسندگان
چکیده
The experimental demonstration of a novel integrated optical isolator concept is presented. By using a transversely magnetized ferromagnetic metal as the electric contact of an active waveguide structure, the transverse magneto-optic Kerr effect induces nonreciprocal loss of the TM guided mode. Based on this principle we designed, fabricated and characterized the first version of an optical isolator easily integrable with standard InP-based active devices. Experimental results on these first demonstrators show an isolation ratio of 2.0 dB/mm.

متن کاملIntegrated Microwave Photonic Isolators: Theory, Experimental Realization and Application in a Unidirectional Ring Mode-Locked Laser Diode
A novel integrated microwave photonic isolator is presented. It is based on the timed drive of a pair of optical modulators, which transmit a pulsed or oscillating optical signal with low loss, when driven in phase. A signal in the reverse propagation direction will find the modulators out of phase and, hence, will experience high loss. Optical and microwave isolation ratios were simulated to b...

Abstract: Phase matching between the fundamental TE and TM modes is an essential condition for complete polarization rotation in magnetooptic waveguides with longitudinally directed magnetization. This condition can be satisfied with embedded square waveguides or with raised strip waveguides, provided that the core dimensions are suitably chosen. Based on coupled mode theory for the vectorial m...

متن کاملIntegrated Optical Isolators
Integrated optical isolators will become necessary as optical networks continue to grow and the need for monolithic integration and greater functionality increases. This thesis presents a design for a polarization independent isolator which can be monolithically integrated with semiconductor lasers. Theory and measurements are used to select a material for the isolator. A polarization independe...
