An electrically tunable MEMS based out-of-plane metamaterials THz filter using stress-induced curved cantilevers to form split-ring resonator in three-dimensional configuration is experimentally demonstrated and characterized. While the achieved tunable range for the resonant frequency is 0.5 THz at 20 volts bias, quality factor of the resonant frequency is improved as well. This MEMS based THz filter using curved cantilevers shows its potential in tunable metamaterials applications such as sensors, optical switches, and filters, etc.

A linear array of MEMS corner cube retro-reflectors (CCR) fabricated with the MUMPs polysilicon surface micromachining process is presented. The CCR's opening faces straight upwards, providing ease of use and better field of view. Tunability can be achieved by employing a drivable mirror as one of the CCR's three mirrors. A novel idea of assembling an N × N CCR array is also proposed.

We propose and experimentally demonstrate microring resonators with transmission width (Q-factor) tuning capability. The width-tuning is performed by ultra-small comb-drive actuators. Transmission width can be tuned from 1nm to 0.14nm range for a resonant mode. Also 15dB transmission drop is obtained.

We propose a simple fabrication method for a dual-axis polymer MEMS mirror made of negative photoresist SU-8 containing magnetic nanoparticles as a magnetically driven actuator. The proposed mirror is driven by magnetic attractive force using external magnetic field. So, it doesn't need complex wiring patterns and can simply fabricate by photolithography only. For evaluation of drive characteristics of the proposed mirror, we measured static deflection angle and frequency response of the fabricated mirror by using a laser position sensor. As a result, we obtained optical deflection angle ±15deg. and the second resonant frequency 29.2Hz of torsional oscillation.

Potentials of the transparent polyimide (PI) substrate were investigated for a possible biological cell culture sheet. Stromal marrow cells (OP9) were used to test the cell culture characteristics, and the OP9 cell culture was compared on three kinds of polymer films of transparent PI, parylene (PA), and polyetheretherketone (PEEK). Microtrenches with the width of 5 μm and the depth of 5 μm were fabricated using hot embossing technique on these films. The cultured cell of OP9 was observed on the transparent PI sheet and PA sheet, but not on PEEK sheet. The culture of OP9 cells were easily observed on the transparent PI sheet using an optical microscope.

Silicon-organic hybrid (SOH) integration can extend the capabilities of silicon photonics by combining silicon-on-insulator (SOI) waveguides with functional organic cladding materials. This enables energy-efficient electro-optic modulators and ultra-compact phase shifters. We review recent progress in SOH integration, discussing both fundamental device concepts and experimental demonstrations.

An electromagnetically actuated MEMS mirror with precise tilt angle control for a bi-state optical switch is reported. A tilt angle control of ± 2.29° is achieved by utilizing the 4 μm BOX layer thickness of an SOI wafer together with carefully controlled backside deep silicon etching to construct precise mechanical stoppers. The device is die level packaged with a KOH etched textured silicon encapsulation to prevent scattering reflection from the back cavity to promote high contrast. Measurement results of tilt angle versus applied magnetic field correspond well with theoretical model prediction. The designed device is suitable for optical telecommunication in harsh environments that do not permit any electrical sparks.

Recent advances in sub-wavelength nanoscale platforms have afforded the control of light from first principles, with impact to optoelectronics and high-density secure communications. In this talk I will highlight two coherent examples where emerging mesoscopic systems can make a difference. Firstly, I will report on chip-scale Kerr frequency comb oscillators, where we have recently observed one of the shortest (74-fs) pulse mode-locking till date (Figure 1a) [1]. The frequency comb dynamics, evolution and coherent nature will be described. The CMOS-compatible frequency combs [2-5], including solitary pulses, have potential to link the RF and optical domains with low phase noise, with implications to precision optical clocks and ultrashort pulse generation.
