Silicon photonics is widely acknowledged as a game-changing technology, driven by the
needs of datacom and telecom. Silicon photonics builds on highly capital-intensive …

We propose a multimode interference coupler (MMI) design for high-index-contrast
technologies based on a shallowly etched multimode region, which is, for the first time to our …

We propose a novel optical 90 ^∘ hybrid consisting of a paired-interference based 2 \,*\, 4
multimode interference (MMI) coupler, a phase shifter and a 2 \,*\, 2 MMI coupler. We …

We demonstrate an on-chip coherent mode scrambling demultiplexer for polarization
multiplexed few mode signals. The device has been fabricated in the standard silicon-on …

We consider an electro-optic phase chaos system with two feedback loops organized in a
parallel configuration such that the dynamics of one of the loops remains internal. We show …

The integrated optical 90-degree hybrid is a crucial component for coherent receivers. Here,
we simulate and fabricate a 4?×? 4 multimode interference coupler as a 90-degree hybrid …

We consider a semiconductor laser with external optical feedback operating at a regime for
which the delay time signature is extremely difficult to identify from the analysis of the …

We propose an ultra-compact optical 90° hybrid with the smallest length of 107μm,
consisting of a wedge-shaped 2× 4 MMI coupler connected with a 2× 2 MMI coupler using …

Broadband, low-loss, and fabrication-tolerant photonic passives are of paramount
importance in any photonic integrated circuit (PIC). Among others, the adiabatic couplers …

We propose a novel optical 90° hybrid employing a paired-interference-based tapered 2× 4
multimode interference coupler and a 2× 2 multimode interference coupler. It was …
