Nonvolatile switching is still a missing functionality in current mainstream silicon photonics complementary metal‐oxide‐semiconductor platforms. Fundamentally, nonvolatile switching stands for the ability to switch between two or more photonic states reversibly without needing additional energy to hold each state. Therefore, such a feature may push one step further the potential of silicon photonics by offering new ways of achieving photonic reconfigurability with ultrasmall energy consumption. Here, a detailed review of current developments that enable nonvolatile switching in silicon photonic waveguide devices is provided. Nonvolatility is successfully demonstrated either based on device engineering or by hybrid integration of silicon waveguides with materials exhibiting unique optical properties. Furthermore, several approaches with high potential for evolving toward a nonvolatile behavior with enhanced performance are also being explored. In most cases, many development steps are still necessary to ensure reliable devices. However, this research field is expected to progress in the coming years boosted by current and emerging applications benefiting from such functionality, such as new paradigms for photonic computing or advanced reconfigurable circuits for programmable photonic systems.

“…The circuit seems to be partial or quasi-adiabatic logic style since ground is connected to MP2. However, according to the circuit construction, energy is not lost during logic transitions and is fully recovered back to the power supply, therefore, the design has followed standard or fully-adiabatic logic technique [25][26][27]. The working of the circuit is almost similar to that 2PASCL as both the circuits use one additional pMOS, configured as a diode across the power supply (PCK) and load capacitor.…”

Decreasing power consumption is the leading challenge for very-large-scale-integrated (VLSI) designers. This paper introduces an innovative prototype for a power-efficient standard or a fully-adiabatic binary-coded-decimal (BCD) 8421 to Excess-3 (XS-3) code converter. The proposed design is compared with traditional complementary metal oxide semiconductor (CMOS) as well as two popular fully adiabatic logic families: adiabatic dynamic CMOS logic (ADCL) and two phase clocked adiabatic static CMOS logic (2PASCL). This investigation was conducted at frequencies ranging from 100 to 900 MHz. The circuit employs 0.3µm CMOS technology, with channel length and width set at 0.3µm and 0.75µm, respectively. The power savings for the proposed logic at 500 MHz when compared to standard CMOS logic, ADCL, and 2PASCL are 54.54%, 28.57%, and 16.67%, respectively

In this work, a dual-side parabolic structural (DSPS) multimode interference (MMI) thermo-optic (TO) waveguide switch is designed and fabricated by using novel low-loss fluorinated photopolymer materials. Comparing with the traditional dual-side linear structural (DSLS) MMI device, the effective length of the MMI coupling region proposed can be effectively reduced by 40%. The thermal stability of the waveguide material is analyzed, and the optical characteristics of the switching chip are simulated. The actual performances of the entire MMI switch are measured with an insertion loss of 7 dB, switching power of 15 mW and an extinction ratio of 28 dB. In contrast to the traditional MMI optical switch, the new type of parabolic structural MMI TO waveguide switch exhibits lower power consumption and larger extinction ratio. The compact fluorinated polymer MMI TO switches are suitable well for realizing miniaturization, high-properties, and lower cost of photonic integrated circuits.
