Arbitrary ratio power splitters using angled silica on silicon multimode interference couplers

Multimode interference photonic switches

“…40,41 After that, several photonic switches have been proposed using the IM inside the MMI section to modify the phase relation between the self-images. 9,37,[42][43][44][45][46][47] The switching mechanism of all these switches is the same-they operate by modifying the refractive index at specific areas within the MMI waveguide, which are collocated with the occurrence of multiple self-images.…”

“…4,5 At the same time, this can be applicable in splitters and combiners, 6 mode converters, 7 and power splitters with arbitrary splitting ratio. 8 Only recently, their use has been expanded from passive to active devices, and several photonic switches have been proposed using MMI effects.…”

Sensors in Biomolecular Interaction Analysis and Pharmaceutical Drug Screening

“…Limits of detection are about 10 pg/mm 2 [75]. Today the costs of manufacturing such devices are prohibitive, but the implementation of IO devices in silicon or in polymers may change this [76,77]. For example, Bookham Technology (UK) is developing integrated solutions based on its patented ASOC TM silicon technology.…”

CMOS-compatible thermal compensator based on a modified Mach-Zehnder interferometer

“…With the temperature increased, the transmission phase change of two arms Δθ 1 and Δθ 2 is supposed to be positive, on the contrary, if the whole MZI Δθ was designed to be negative with special arms, thus, the thermal compensator could be achieved. *zjzhou@pku.edu.cn; phone +86 010-62767875; fax +86 010-62759808; In the MZI thermal compensator, the 3dB splitter can be realized with multimode interference (MMI) [15][16]. The optical field E in after the input coupler is separated into E 1 and E 2 equally.…”
