“…Although different in application, recent published chips with similar requirements integrate a great number of optical power monitors and phase shifters. For example, two recent demonstrations integrate 900 optical power monitors and 448 phase shifters 37 and 1024 phase shifters 38 , respectively, in footprints <300 mm 2 . Equally important is the correct management of the complexity of optimization algorithms and circuit programming.…”

Programmable integrated photonic circuits have been called upon to lead a new revolution in information systems by teaming up with high speed digital electronics and in this way, adding unique complementary features supported by their ability to provide bandwidth-unconstrained analog signal processing. Relying on a common hardware implemented by two-dimensional integrated photonic waveguide meshes, they can provide multiple functionalities by suitable programming of their control signals. Scalability, which is essential for increasing functional complexity and integration density, is currently limited by the need to precisely control and configure several hundreds of variables and simultaneously manage multiple configuration actions. Here we propose and experimentally demonstrate two different approaches towards management automation in programmable integrated photonic circuits. These enable the simultaneous handling of circuit self-characterization, auto-routing, self-configuration and optimization. By combining computational optimization and photonics, this work takes an important step towards the realization of high-density and complex integrated programmable photonics.

“…After that, the port number of silicon photonic switches increased dramatically. For example, Tanizawa et al [247] reported a fully packaged 32 Â 32 silicon photonic TO switch using land grid array (LGA) packaging technology. Recently, an ultra-lagre scale TO silicon photonic switch was demonstrated with very low crosstalk and moderate insertion loss [248].…”

“…The switch chip is equipped with a simple spot size converters (SSCs) with inverse taper. The detailed designs and performances of the element switch and the intersection are reported in [3] and [4]. The dual 4×4 switch chip is die-bonded to a ceramic chip mount as shown in Fig.…”

“…It was reported that an 8×8 strictly non-blocking optical switch using Mach-Zehnder interferometer (MZI) based on Si thick-rib waveguides achieved polarization-independent operation [1]. On the other hand, optical switches based on Si-wire waveguides have attractive features of ultra-small footprint [2]- [4], monolithic integration of CMOS control driver [5], and high fabrication yield without precise thickness control of Si layer. However, Si-wire optical switches with widely-used waveguide dimensions of approximately 220×430 nm 2 have strong polarization dependence due to its asymmetric mode profile with tight light confinement.…”
