We demonstrate an efficient guided-mode resonant color filter array. It consists of a thin subwavelength silicon nitride grating and a homogeneous silicon nitride waveguide on a glass substrate. The fabricated device exhibits high experimental efficiencies.
InGaN micro-light emitting diodes on Si substrates have been fabricated and characterized. Their abilities for micro-display, high modulation bandwidth of 270 MHz and data transmission rate of up to 400 Mbit/s have been demonstrated.
Mode transformers between very compact substrate removed waveguides and very big polymer waveguides were designed and fabricated. Transition loss between two types of waveguides was quantified and 7 dB insertion loss improvement was measured.
We report flexible tapes of high-performance, top-emitting, quantum dot based, light-emitting diodes (QLEDs) with multicolor emission, actively working even when flexed. The resulting QLED tapes reach a high peak luminance level of 19,265 cd/m2.
This invited paper overviews Corning® Willow™ Glass substrates and their enabling of new display and lighting applications, devices, and materials. Specific focus is put on flexible glass' mechanical reliability, R2R processing, and organic electronic devices.
Compound semiconductor electro-optic modulators based on substrate-removal are described. Modulators with metal and buried electrodes in bulk GaAs have Vπ of 5 V and 0.3 V respectively. For both types bandwidths exceeding 35 GHz were also demonstrated.
We report the fabrication of a mechanically-flexible 16×16 array of thin-film, micron-size LEDs emitting at 480 nm. Devices were transfer-printed onto a mechanically-flexible ITO backplane using a modified, high-precision (placement accuracy ±25 nm) assembly system.
Resonant narrowband out-coupler designs for laser systems leave a portion of the device exposed to damage and contamination. We present a fabrication method for full device encapsulation, resulting in a highly reflective, protected spectral filter.
Vertical cavity surface emitting lasers (VCSELs) are an important light source for applications in communication and appliances consumer use. However, the types of III-V semiconductor materials that can be used to manufacture monolithic VCSELs are limited to only few choices. Moreover, limitations of the device materials will also limit the functionality of VCSELs incorporated into microsystems. Various...
We demonstrate the plasmonic properties of double gold nanotube structures using the finite difference time domain (FDTD) method, and present the techniques that we have used to fabricate them on cyclic olefin polymer (COP) substrate.
We present experimental evidence of the rapid exchange of diffracted power between the reflected zero-order wave and a substrate wave across a small angular range. This effect enables resonant devices we call Rayleigh reflectors.
We present the development of InAs/GaAs quantum-dot devices monolithically grown on Si substrates for silicon photonics. Room-temperature cw lasing at 1.3 µm has been demonstrated for the InAs/GaAs quantum-dot devices on Si substrates.
A simple fabrication approach of replicating nanoscale patterns with 300-nm periods on thermoplastic polymethyl methacrylate substrates using thermal nano-imprint lithography is reported. The resonant structures hold potential application in light trapping for thin-film solar cells.
We directly measured the nanoscale dynamics of hydrogen induced lattice expansion and deformation of palladium thin films in-situ. These results provide several key material parameters needed for designing high performance optical hydrogen sensors.
Various lasers and light sources on Si via heterogeneous integration of Si/III–V have been reported based on direct growth on Si [1] or wafer bonding technology [2–4]. We reported earlier optically-pumped Si membrane-reflector vertical-cavity surface-emitting lasers (MRVCSELs) fabricated by low-temperature membrane transfer printing processes [5, 6]. Here we report electrically-pumped devices based...
We report an investigation of the effects of variation of composition on the properties of YIG (yttrium iron garnet) films grown on YAG substrates by multi-beam pulsed laser deposition (PLD).
