Very Low-Power, Polarization-Independent, and High-Speed Polymer Thermooptic Switch

This letter demonstrates the design and experimental verification of a very low-power consuming, polarization-independent, and high-speed polymer Mach-Zehnder 2 × 2 photonic switch. This thermooptic switch operated with less than 4 mW of power consumption via a small-area heater. This device is, to the authors best knowledge, the most efficient and practical polymer photonic switch operating with polarization independence and low crosstalk of less than -25 dB.

Very Low Power Operation of Compact MMI Polymer Thermooptic Switch

This letter demonstrates a compact, very low power consumption, and low crosstalk multimode interference coupler-based polymer thermooptic photonic switch. The fabricated thin-film small-area heater confirmed the simulation results with operating power consumption as low as 8.9 mW. The switching crosstalk obtained was less than - 23 dB.

Design and performance of low-power, high-speed, polarization-independent and wideband polymer buried-channel waveguide thermo-optic switches

This paper analytically and experimentally investigates and compares the characteristics of two kinds of polymer buried-channel waveguide thermo-optic switches such as 1) a multimode interference (MMI) switch using a single MMI coupler and 2) a Mach-Zehnder interferometer (MZI) switch. Especially, the MZI switch experimentally exhibited low-power consumption of 3.5 mW, high-speed with a response time of less than 200 μs, polarization independence as well as in a wideband of about 80 nm. These low-power consumption, relatively high-speed, and polarization-independent switching characteristics are almost coincident with the designed ones. Furthermore, an improved MZI structure is proposed for lower switching power consumption, and it is expected below 0.5 mW with an enhanced thermal localization structure.

Ultimate-low-power-consumption, polarization-independent, and high-speed polymer Mach-Zehnder thermo-optic switch

We demonstrate a compact, ultimate-low-power-consumption, polarization-independent, and high-speed polymer Mach-Zehnder 2times2 photonic switch. Our thermo-optic switch operates with less than 4mW of power consumption via a small-area heater, which is, to our best knowledge, the lowest value of its switch type reported to date. The polarization independent switching crosstalk is less than -25dB while the switching rise and fall times obtained are 90mus and 160mus, respectively.

Proposal of a Novel MMI-Based NxN Non-Blocking Optical Ring Switch

We propose a novel optical NxN switch network based on MMI elements and a nested rings topology. Reductions compared to the conventional Bene breves network include the number of switching elements, power consumption, and physical device area. As much as 20% reduction to the number of elements is achievable for an NxN switch. An equation has also been derived for the number of switches. Since MMI elements in this type of device are required to operate with bi-directional inputs, passive simulation shows that they can exhibit low losses of 0.1dB with -52dB of crosstalk.

Proposal and design of sub-mW and high-speed polymer thermo-optic switch

Sub-mW power consumption polymer thermo-optic photonic switch is studied and demonstrated. The reported photonic switch operates with a power consumption less than 0.4mW with polarization independence and a very low crosstalk of less than −50dB.

Nonblocking N×N integrated photonic switching architecture using rearrangeable nested rings

We report on a new N×N nonblocking integrated photonic switching architecture based on the novel method of nested rings. In comparison with other architectures, this new architecture shows various advantages such as reduction of the number of switching elements, maintenance of constant low-path difference loss, application of optical feedback, multidirectional port extension for monolithic integration, reduction of waveguide crossovers, and efficient use of the device area for ultracompact integrated switching networks.
