Abstract
Section titled âAbstractâAccess to nanometric feature sizes with standard lithography and manufacturing processes in commercial foundries has recently spurred interest in design of advanced nanophotonic circuits. The scalability of such systems and the prospect of tight integration with electronics provide a path for miniaturization and addressing new functionalities. Research at the recently established EPFL Q-LAB focusses on engineering challenges in Nano-Opto- Electromechanical systems. In this contribution, we summarize recent advances in nano-opto- electromechanical systems in three examples: (I) MEMS movable nano-optical waveguides on an integrated silicon photonics platform allow efficient optical switching on chipscale [1]. Dense integration of MEMS silicon photonic switches has been demonstrated with a an array of 50x50 individually addressable switches on a single chip of response time and low switching excess loss (1.5dB). Challenges presented by large-scale integration on chip-level can be met by including efficient addressing schemes [2]. (II) Tight integration of silicon photonic circuits with CMOS electronics allows single-chip integration of an opto-electronic feedback loop for LIDAR ranging with sub-mm range resolution [3]. (III) Exploiting radiation pressure based optomechanical interaction in nano-opto- electromechanical resonators, oscillators for frequency reference applications can be batch- fabricated on wafer-level. With precise control of the fabrication processes, with optical and mechanical design, and exploiting singleand multi-material systems such as silica, silicon and/or diamond, low-phase noise optomechanical oscillators can be designed: Engineering the optical Q-factor allows optomechanical excitation of parametric oscillation, and increasing mechanical Q-factors is hereby essential to reduce the phase noise in optomechanical oscillators for potential practical applications [4].
