Four-channel integrated-optic wavelength demultiplexer with weak polarization dependence

Packaged PHASAR-based wavelength demultiplexer with integrated detectors

For the first time, PHAS AR-based wavelength demultiplexers with integrated detectors have been packaged in an industry-standard Butterfly-type module. 8-Channel nearly polarisation-independent operation is demonstrated. In addition, 4nm tuning is realised.

An 8-Channel Wavelength MMI Demultiplexer in Slot Waveguide Structures

We propose a novel 8-channel wavelength multimode interference (MMI) demultiplexer in slot waveguide structures that operate at 1530 nm, 1535 nm, 1540 nm, 1545 nm, 1550 nm, 1555 nm, 1560 nm, and 1565 nm. Gallium nitride (GaN) surrounded by silicon (Si) was found to be a suitable material for the slot-waveguide structures. The proposed device was designed by seven 1 × 2 MMI couplers, fourteen S-...

Novel Four-Channel All Optical Demultiplexer Based on Square PhCRR for Using WDM Applications

Ring resonators have always been referred to as a highly flexible structurefor designing optical devices. In this study, we have designed and simulation a fourchannel optical demultiplexer using square photonic crystal ring resonator. The squarelattice constant for this purpose structure is used. The purposed structure has an averagecrosstalk, transmission coefficient, q...

Integrated ultracompact and broadband wavelength demultiplexer based on multi-component nano-cavities

Integrated nanoscale photonic devices have wide applications ranging from optical interconnects and optical computing to optical communications. Wavelength demultiplexer is an essential on-chip optical component which can separate the incident wavelength into different channels; however, the experimental progress is very limited. Here, using a multi-component nano-cavity design, we realize an u...
