Jorge Parra received his Ph.D. in the topic of silicon photonics from the Universitat Politècnica de València (UPV), Spain, in 2022. He is currently a postdoctoral researcher at the Nanophotonics Technology Center (NTC), UPV, where he is involved in designing, simulating, and characterizing both passive and active photonic integrated devices. His research interests focus on integrated photonics, especially in silicon photonics, and the integration of CMOS-compatible materials with unique optoelectronic properties, such as phase-change materials, to bring new functionalities to the silicon photonics platform.
The exponential growth of photonic integrated circuits (PICs) has been driven by their scalability and ability to harness light’s benefits. Among various platforms, silicon (Si) photonics stands out due to its compatibility with complementary metal-oxide-semiconductor (CMOS) fabrication and electronic integration, meeting the demands of applications such as data communications, artificial intelligence, quantum computing, and healthcare. However, the modest active properties of silicon challenge its adaptability to emerging needs. To overcome this, we have explored integrating CMOS-compatible materials—phase-change materials (PCMs) and transparent conductive oxides (TCOs)—with Si photonics. In this talk, I will present recent hybrid PCM/Si and TCO/Si photonic devices offering new functionalities such as reconfigurability, optical storage, strong nonlinearities, and neuromimetic optical response, expanding the horizons of Si photonics technology.
