With success of silicon photonics having mature to foundry-readiness, the intrinsic limitations of the weak electro-optic effects in Silicon limit further device development. To overcome this, heterogeneous integration of emerging electrooptic materials into Si or SiN platforms are a promising path to deliver <1fJ/bit device-level efficiency, 50+Ghz fast switching, and <10's um^2 compact footprints. Graphene's Pauli blocking enables intriguing opportunities for device performance to include broadband absorption, unity-strong index modulation, low contact resistance. Similarly, ITO has shown ENZ behavior, and tunability for EOMs or EAMs. Here we review recent modulator advances all heterogeneously integrated on Si or SiN such as a) a DBR-enabled photonic 60 GHz graphene EAM, b) a hybrid plasmon graphene EAM of 100aJ/bit efficiency, d) the first ITO-based MZI showing a VpL = 0.52 V-mm, and e) a plasmonic ITO MZI with a record low VpL = 11 V-um. We conclude by discussing modulator scaling laws for a roadmap to achieve 10's aJ/bit devices.

Elastomeric mirror is one of the main components of systems that require tunable optical characteristics, and is being applied in various devices such as optical zoom camera, electrostatic actuator, and augmented/virtual reality (AR/VR) display. Generally, to fabricate an elastomeric mirror, a metal layer is deposited on an elastomer substrate by vacuum process such as thermal evaporation, e-beam evaporation, and sputtering. However, these processes can damage the elastomeric substrate, thereby degrading the quality of the mirror surface. The metal layer formed on the elastomeric substrate is also vulnerable to small deformation, which limits applications of elastomeric mirror. In this work, we report all-solution-processed elastomeric mirror film whose constituent layers were deposited sequentially by spin coating and dip coating method. The film consists of polydimethylsiloxane (PDMS) base, aluminum (Al) mirror, and PDMS encapsulation layer. As a material of mirror layer, we selected a ‘mirror ink’, which composed of Al powder, organic solvent, adhesive and mainly used for screen printing. We adjusted the dilution concentration of mirror ink to make it suitable for the solution process and controlling the roughness of the coated mirror layer. In addition, there was no damage to the mirror layer against deformation due to the presence of encapsulation layer, so it can be attachable well to the curved surface. As an example of application, we demonstrated a seamless display system by placing the elastomeric mirror between two curved panels. We expect that our elastomeric mirror will be applicable to various tunable optical systems.

Mid-Infrared (Mid-IR) techniques have gained considerable attention because of their inherent molecular selectivity and their potential for rapid label-free detection in applications such as water quality and environmental monitoring, security, food safety, and point-of-care diagnostics. Waveguide evanescent-field-based Mid-IR spectroscopy can detect analytes at very low concentrations using molecular absorption fingerprints, potentially offering high sensitivity and selectivity over a wide range of compounds. Moreover, significant footprint reduction compared to ATR-based FTIR measurements can be achieved with optical waveguide-based Mid-IR sensing through integration of various optoelectronic and microfluidic components realizing fully packaged lab-on-a-chip systems. Recently we have developed low-loss chalcogenide optical waveguides and demonstrated waveguiding in the mid-wave and long-wave infrared spectral bands. High contrast GeTe4 and ZnSe channel waveguides were fabricated on bulk substrates and on silicon wafers (with suitable optical isolation layers) using lift-off and dry etching techniques after photolithographically patterning the thin films. These waveguides were exhibiting optical losses as low as 0.6 dB/cm in the mid-wave IR band and were validated for the Mid-IR evanescent wave spectroscopy with water and IPA. We have also demonstrated the effectiveness of simple paper-based fluidics with our waveguides. In addition, we investigate a new family of free-standing Ta2O5 rib waveguides for trace gas detection with evanescent field overlap with the surrounding medium (air) up to about 70%. The waveguides are being fabricated and the fabrication and characterization results will be presented.
