In this paper we present 1× 4 wavelength demultiplexer operating at 1.4 μm, 1.45 μm, 1.5
μm and 1.55 μm wavelengths, based on multimode interference (MMI) coupler in slot …

An ultra-compact 1310/1550 nm wavelength demultiplexer based on multimode interference
(MMI) coupler assisted by subwavelength gratings (SWGs) is proposed. Two parallel SWG …

A 2× 2 tapered multimode interference (MMI) coupler is designed and fabricated by using air-
cladded SU-8 rectangular waveguide, which is effective in reducing the device size and …

We propose a novel design of integrated polarization splitter/combiner with ultra wide
bandwidth. The proposed design utilizes the electro-optic (Pockels) effect in GaAs for …

We propose a new compact optical switch that works over a wide wavelength band. This
switch has low cross talk and can be easily integrated with other components of the …

The design and performance analysis of a 1310/1550-nm wavelength division demultiplexer
with tapered geometry based on InP/InGaAsP multimode interference (MMI) coupler has …

This letter presents a design for diminishing the polarization-dependency of a Si nanowire-
based multimode interference (MMI) coupler by using a tapered MMI section. The entrance …

A designprocedure for an arbitrarily tapered multimode interference (MMI) coupler based on
Si nanowaveguides is presented. First a series of the effective indices of the zeroth and first …

Multimode interference (MMI) couplers have received more attention in recent years due to
their significant role played in telecommunications. Their unique features are compactness …
