Different lasing modes including in-phase modes, out-of-phase modes and special mixture modes are obtained from Ht-implantation-defined coherently coupled VCSEL arrays by engineering the interelement spacings between elements. The simulated far-field patterns match the experiments well.

Compact visible microdisk lasers consisting of InGaP/ InGaAIP multi-quantum wells were fabricated and embedded in a deformable polydimethylsiloxane (PDMS) polymer substrate. In addition to very small device footprint and low-threshold, the wavelength of microdisk lasers can be linearly fine-tuned by stretching the flexible substrate. A smooth wavelength tuning of 1.5 nm and 2.6 nm for microdisk lasers with the diameter of 1.2 μm and 1.5 μm are demonstrated under 36% strain, respectively. The compact tunable visible microdisk lasers can not only function as a novel light source for photonic integrated circuits but also sensitive and skin-attachable gauges in local index and strain detection for stretchable electronics.

We propose the use of through-focus scanning optical fluorescence microscopy for marine phytoplankton count. The phytoplankton in a seawater container of 20 ⨯ 20 ⨯ 20 mm is excited by a LED of 435 nm and the fluorescence emission from the phytoplankton over 656 nm is imaged into the image detector (CCD)through an objective lens and a tube lens. The proposed method stacks the sectioned image of the sea water in the container as it optically moves the image plane vertically along the optical axis by moving the tube lens. We built a prototype and it was demonstrated to count the phytoplankton of 1cc (10⨯10⨯10mm)volume with a spatial resolution less than 10 μm in one second.

We demonstrate a lattice of 3D chiral plasmonic nano-holes, with strong relative optical circular dichroism ~0.5 and high Q-factor up to 45. The area of the lattice can be fabricated to 1cm2 with nearly perfect consistency of every unit cell. We show that this CD enhancement is due to the interaction between the chiral response of the chiral holes and the scattering modes of the lattice.
