“…Finally, a protective micron thick silica cladding would be deposited via plasma enhanced chemical vapor deposition. It should also be noted that the ability to provide arbitrary power ratio does not come at the expenses of a large footprint or reduced bandwidth, which are comparable to recent solutions based on T-junctions and MMI technology [22,23]. For all these reasons, we believe the proposed technology represents a viable solution to implement flexible and compact integrated power splitters for the multimode photonics platform.…”

“…Since multimode photonics is a relatively young field of study, this is a quite recent topic. In 2019 [22], a few-mode 1 × 2 splitter has been proposed providing equal (non-arbitrary) splitting. In 2020 [23], a MMI-based 1 × N equal splitter has been demonstrated working at 1.55 µm, and a T-junction based 1 × 2 splitter [24] has been proposed.…”

We introduce a 1 × N integrated power splitter for the multimode photonics platform. The device converts an input laser beam into a higher-order mode beam, which afterwards is split. The core of this setup is represented by a non-uniform array of N waveguides that allows achieving arbitrary power splitting. The system exhibits high modal purity and is tested against wavelength variations and fabrication errors. The possibility to include a multi-input port configuration, leading to various power ratios via a single device, provides further flexibility. Our analysis is validated by finite-element-method simulations. At the best of our knowledge, this represents the first design of a device for arbitrary 1 × N power splitting of higher-order modes.

“…MMI and DC splitters are commonly used in coupler structures. Multimode interference and coupled-mode theories are used to analyze MMIs and DCs [18,41,42] . However, these analytical methods do not consider the radiation field of the devices; as such, these methods cannot accurately calculate device performance and require the use of other numerical methods, such as the finite difference timedomain algorithm.…”

Powerful electronic design automation tools have enabled the rapid development of electronic Integrated Circuits (ICs). Similar to electronic ICs, silicon photonics technology has sufficiently matured, and large-scale photonic circuits can now be implanted into a single chip. Design tools have also evolved from primary devices to complex photonic circuits. In this paper, we review the current state of photonic design automation in terms of device modeling methods and circuit simulation methodologies, and compare the photonics design flow with mature electronic design automation design flows. Key challenges and opportunities are also discussed.

“…Very few works have been reported for polarization-insensitive or mode insensitive MPS using subwavelength structures [19], three-coupled silicon rib waveguides [20] and MMI [21][22][23]. MPS has been reported using MMI structure for TE 00 , TE 01 , TE 10 and TE 11 modes [24]. However, we have proposed the mode insensitive MMIbased MPS (TE 0 , TE 1 and TM 0 ) with ultra-compact footprint, low loss and large bandwidth.…”

A mode insensitive mode power splitter (MPS) based on multimode interference has been designed using silicon on insulator. The device supports fundamental and first-order transverse electric (TE) and fundamental transverse magnetic (TM) mode (TE 0 , TE 1 , and TM 0 ) having minimum excess loss of 0.06 dB at input of 1550 nm wavelength, and less than 0.5 dB for a broad wavelength of 1410-1690 nm. Moreover, the proposed mode splitter has a low mode dependent loss (MDL) of 0.02 dB at 1550 nm and supports broad bandwidth of 280 nm having MDL <0.4 dB. The proposed MPS can be a useful mode division multiplexing component for optical networks.
