Walaupun suis get semua-optik berdasarkan penyerapan intersubband dalam telaga kuantum nitrida diramalkan beroperasi pada 1 Tb/s, realisasi penyerapan intersubband yang kuat pada panjang gelombang komunikasi optik masih sukar. Pendekatan alternatif ialah suis pintu jenis interferometer yang menggunakan perubahan indeks biasan disebabkan oleh penyerapan intersubband bagi nadi kawalan pada panjang gelombang yang lebih panjang. Kebolehlaksanaan suis get Mach-Zehnder interferometer (MZI), di mana denyutan 1.55-µm dikawal oleh denyutan 1.85-µm, secara teorinya disiasat oleh simulator domain masa perbezaan terhingga (FDTD). Walaupun peralihan fasa berkesan tidak mencapai π, 22.5% daripada tenaga nadi isyarat diramalkan akan dikawal oleh nadi kawalan 10-pJ dalam suis MZI. Malah denyutan 1.3-µm boleh dikawal oleh denyutan 1.85-µm dengan mengorbankan tenaga pensuisan. Pendekatan ini menyediakan cara untuk memproses denyutan isyarat pada panjang gelombang komunikasi optik menggunakan penyerapan intersubband yang kuat pada panjang gelombang yang lebih panjang.

Abstract: Although all-optical gate switches based on the intersubband absorption in nitride quantum wells are predicted to operate at 1 Tb/s, realization of strong intersubband absorption at the optical communication wavelength is still difficult. An alternative approach is an interferometer-type gate switch utilizing refractive index change due to the intersubband absorption of a control pulse at a longer wavelength. Feasibility of Mach-Zehnder interferometer (MZI) gate switches, in which 1.55-µm pulses are controlled by 1.85-µm pulses, was theoretically investigated by finite-difference time-domain (FDTD) simulator. Although the effective phase shift does not reach π, 22.5% of the signal pulse energy was predicted to be gated by a 10-pJ control pulse in the MZI switch. Even 1.3-µm pulses can be controlled by 1.85-µm pulses at the expense of the switching energy. This approach provides a way to process signal pulses at the optical communication wavelength utilizing strong intersubband absorption at a longer wavelength.
