We present a method to efficiently separate the rectangularly symmetric modes of light with two phase-only holograms. The holograms, known as fan-out elements, can split the input modes into multiple copies. A subsequent lens focuses these modes to d

A thermo-optic phase shifter is of great importance in silicon photonics. However, it is difficult to simultaneously achieve a good performance in insertion loss and in response speed by using traditional thermal tuning through a metallic heater. In

For most photonics devices and systems, loss is desperately averted, since it will increase the power consumption and degrade the performance. However, in some non-Hermitian systems, loss can induce a modal gain when the parity-time symmetry is broke
