“…Recently, OPSs have been widely used in fiber-optic communication systems and some novel OPSs are reported based on multimode interference (MMI) principle. [1][2][3] OXCs are current under development 4,5 and demonstrated using various approaches such as micro-electro-mechanical system (MEMS) 6 , Silica-on-silicon 7 , SiO 2 -GeO 2 with an MMI geometry 8 , etc. From the viewpoint of the advancement in integrated optics, development of microphotonic switches with more reliability and compactness can be achieved by integrating OPS and OXC.…”

A microphotonic switch with three input waveguides and two output waveguides and integrated with an optical power splitter has been proposed. It is fabricated on the multimode interference principle in Si-based SiGe material system and configured for a 3× 2 symmetrical structure of the three input waveguides and the two output waveguides of the device. The central waveguide section is based on a multimode interference and incorporated with an activated carrier injection element. The operating wavelengths of the device are specially designed for 1545, 1550, and 1555 nm conventional-band wavelengths. The measured crosstalk is at around −17 dB and the average insertion loss is about 2.3 dB. At switch-ON state, the measured injection current is 370 mA corresponding to an injection current density of 950 A/cm 2 .

“…Waveguide splitter networks that divide an optical signal into N outputs (1 × N) are important elements in a variety of applications including power splitters for planar lightwave circuits (PLCs) [1,2] and periodic optical sources for integrated microfluidic devices [3,4]. Such splitter networks are primarily based on either cascaded Y-branch splitters [1][2][3]5,6] or multimode interference (MMI) splitters [4,[7][8][9]. In this paper we report an alternate approach using trench-based splitters (TBSs) [10,11] and trench-based bends (TBBs) [12].…”

We demonstrate compact waveguide splitter networks in siliconon- insulator (SOI) rib waveguides using trench-based splitters (TBSs) and bends (TBBs). Rather than a 90 degrees geometry, we use 105 degrees TBSs to facilitate reliable fabrication of high aspect ratio trenches suitable for 50/50 splitting when filled with SU8. Three dimensional (3D) finite difference time domain (FDTD) simulation is used for splitter and bend design. Measured TBB and TBS optical efficiencies are 84% and 68%, respectively. Compact 105 degrees 1 x 4, 1 x 8, and 1 x 32 trench-based splitter networks (TBSNs) are demonstrated. The measured total optical loss of the 1 x 32 TBSN is 9.15 dB. Its size is only 700 microm x 1600 microm for an output waveguide spacing of 50 microm.

“…A variety of structures have been developed for power splitting, including the fused optical fiber bundle [1], cascaded Y-branches [2,3], and multimode interference (MMI) [4,5]. Recently emerged applications, such as orthogonal frequency division multiplexing (OFDM) [6], multiple-line laser writing technology [7], multiobject recognition in a multichannel joint-transform correlator [8], and planar optical crossover interconnects [9], all need to split the incident beam into a large number of channels with equal intensity.…”

Abstract. In this paper, we proposed an optical splitter planar waveguide design with super multi channels. The design utilizes the wavefront interference and spatial filtering theory. The DC and AC spatial frequency components of the phase grating are separated spatially, and they are remerged at output plane after specific phase delay is added to the DC spatial frequency component. Therefore, the output field distribution is enhanced in some area and cancelled in the rest area in each period. Finally, the input beam is split into super multi channels. There is only phase modulation in the whole device without any amplitude modulation. Therefore, the insertion loss of the device is very small, theoretically. Besides, for the same branch number, the length of the device is smaller than that of conventional splitters based on Y branch and multimode interference.
