We demonstrate all-optical switching in quantum dots (QDs). The switching is studied in an integrated optical combiner circuit. This is a Mach–Zehnder interferometer with an unequal power distribution over the branches. The refractive index is inte

Unbalanced multimode interference (MMI) couplers are optical integrated components widely used in photonic integrated circuits. Couplers with two fixed coupling ratios: 85/15 and 15/85 are studied in this paper. Low-loss MMI couplers are designed and

A self-switching mechanism in Mach-Zehnder interferometers (MZIs) is described. The input light signal is distributed unequally over the interferometer arms using an multimode interference (MMI) coupler. In the arms, semiconductor optical amplifiers

We report all-optical switching due to state-filling in quantum dots (QDs) within a Mach-Zehnder Interferometric (MZI) switch. The MZI was fabricated using InGaAsP/InP waveguides containing a single layer of InAs/InP QDs. A 1530-1570 nm probe beam is

This study demonstrates that the excitation of the first-order mode in access waveguides can significantly deteriorate the coupling ratio of unbalanced MMI couplers and increase the excess losses. Care, therefore, should be taken in coupling light in

We demonstrate all-optical switching in quantum dots. The switching is studied in an integrated optical combiner circuit. This Mach-Zehnder interferometric device is aimed to avoid an unwanted 3-dB loss, fundamental in passive optical splitters.

We report all-optical switching due to state-filling in quantum dots (QDs). The switching energy is as low as 6 fJ since state-filling requires only 2 electron-hole pairs per QD. The single layer of InAs/InP QDs is inserted within a InGaAsP/InP waveg

An integrated Mach-Zehnder interferometer using self-switching, capable of reducing the saturation induced pattern effect, is reported. The device functionality is shown for 10 Gbit/s, and BER measurements show an improvement of up to 7 dB of the inp
