“…This challenge has stimulated the development of BS devices based not on the differential refraction of optical fluxes but on the principle of diffraction division of an input optical signal into separate beamlets by interaction (transmission) with specially designed diffractive optical elements (DOEs). Thus, such DOEs can be, e.g., ring resonators integrated into photonic crystals [14,15], specially shaped reflecting/transmitting metasurfaces and meta-lattices [11,16,17] providing angular beam separation, as well as planar conventional Y-branch splitters with a complex hierarchy [18].…”

“…Recently, optical splitters based on planar disk or ring traveling/standing wave resonators realized as an integrated element inside photonic crystals [8,15] or directly on a silicon-on-insulator (SOI) platform [4,5,19] have become widespread. Typically, such splitters operate in a narrow spectral band near the eigenmode resonances of a constituting microcavity when the incoming optical radiation is coupled to the resonant modes and is redirected into signal collection channels (drop ports).…”

An optical beam splitter is used for dividing an input optical beam into several separate beams with a specific power ratio. Usually, conventional optical beam splitters have bulky dimensions (many optical wavelengths) and a fixed dividing ratio, which significantly limit the design of new miniaturized optical devices and integrated optical circuits. We propose and investigate in detail a novel physical concept of a highly miniaturized (up to two working wavelengths) planar optical resonant splitter/coupler with a switching element comprising a photonic molecule (PM) pair dispersing input optical fluxes in multiple directions with a tailored power ratio. The structural design of the proposed splitter is based on a silicon-on-insulator (SOI) platform and composed of high-quality resonators in the form of electromagnetically coupled submicron-sized microcylinders. The control on the power division ratio and the selection of optical beam directions is realized by tuning the photonic splitter structure to the corresponding resonance of the PM supermode. Compared to known analogs, the proposed design is easy and cheap in fabrication. Because of its tiny dimensions, it is suitable for integration into a “System-on-a-chip” platform and can dynamically change the beam power division ratio by input wave-phase manipulation.

Optical beam splitter is used for dividing an input optical beam into several separate beams with specific power ratio. Usually, conventional beam splitters have bulky dimensions and fixed dividing ratio which significantly limit the design of new miniaturized optical devices and integrated optical circuits. We propose and investigate a novel physical concept of a miniaturized planar optical splitter/coupler with a switching element in the form of a photonic molecule (PM) pair dispersing input optical fluxes along multiple ways with variable power proportions. The structural design of the proposed splitter is based on a silicon-on-insulator (SOI) platform and composed of high-quality resonators in the form of electromagnetically coupled submicron-sized microcylinders. The control on the power division ratio and the selection of optical beam directions is realized by tuning the photonic splitter structure to the corresponding resonance of PM supermode. Compared to known analogues, the proposed design is easy to fabricate, suitable for integration into a "System-on-a-chip" platform and can dynamically change the beam power division ratio by input wave-phase manipulation.
