چکیده

New, compact multimode interference couplers with tunable power splitting ratios have been realized. Experiments show large tuning ranges. Such couplers are needed to optimize ON–OFF ratios in interferometric devices and may find applications as extremely compact switches.

Variable splitting ratio 2 x 2 MMI couplers using multimode waveguide holograms.

Variable power splitting ratio 2x2 MMI couplers using multimode waveguide holograms are analyzed. Theoretical analysis shows that variable splitting ratios can be obtained with surface relief holograms on MMI couplers with fixed dimensions. Devices with paired-imaging lengths are designed on a silicon-on-insulator (SOI) platform. Beam propagation simulations are used to verify a matrix theory a...

Arbitrary Power Splitting Couplers Based on 3x3 Multimode Interference Structures for All-optical Computing

-Chip level optical links based on VLSI photonic integrated circuits have been proposed to replace metal electrical data paths in cases where high frequencies make electrical traces impractical. This is especially relevant to highspeed clock signals as silicon CMOS circuit technology is scaled higher in speed to the GHz range and beyond. In this paper, the realization of optical couplers and po...

Spatial mode filters realized with multimode interference couplers.

Spatial mode filters based on multimode interference couplers (MMI's) that offer the possibility of splitting off antisymmetric from symmetric modes are presented, and realizations of these filters in InGaAsP/InP are demonstrated. Measured suppression of the antisymmetric first-order modes at the output for the symmetric mode is better than 18 dB. Such MMI's are useful for monolithically integr...

Demonstration of Compact 2x2 Multimode Interference Coupler on Silicon Nanomembrane

We designed and fabricated a 2x2 tapered multimode interference coupler on silicon-oninsulator with dimensions of 12.88μm×3μm. The device keeps a 50/50 splitting ratio over a 50nm bandwidth. To our best knowledge this is the most compact 2x2 MMI demonstrated. ©2010 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.2790) Guided waves

A Thermally Tunable 1 × 4 Channel Wavelength Demultiplexer Designed on a Low-Loss Si3N4 Waveguide Platform

A thermally tunable 1 × 4 channel optical demultiplexer was designed using an ultra low-loss Si3N4 (propagation loss ~3.1 dB/m) waveguide. The demultiplexer has three 2 × 2 Mach-Zehnder interferometers (MZI), where each of the MZI contains two 2 × 2 general interference based multimode interference (MMI) couplers. The MMI couplers exhibit −3.3 dB to −3.7 dB power division ratios over a 50 nm wa...
