We describe a low-loss single-mode waveguide in planar light-wave circuit (PLC) glass doped with boron and phosphorus, which is more difficult to write than pure-silica glass. The written waveguide… (More)
We designed temperature-insensitive dual-polarization optical hybrids for the coherent receivers, and firstly demonstrated temperature-insensitive performance with a polarization extinction ratio… (More)
We demonstrate a compact dual polarization optical hybrid achieved by the integration of polarization beam splitters and 90°-hybrids using silica-based planar lightwave circuit. The fabricated device… (More)
We fabricated an ultra-compact InP-based DP-QPSK modulator by the hybrid integration of an InP twin-IQ modulator and a PLC polarization multiplexing circuit for the first time. 112-Gb/s DP-QPSK… (More)
We propose a new PLC design for a 43 Gb/s DQPSK demodulator. The design reduces both the module size and the power consumption without degrading any of the module characteristics.
The extension of optical add/drop multiplexing (OADM) systems to metro-core and metro-access networks has led to the need for economical and compact OADM devices. In this paper, we demonstrate a… (More)
Apoptosis plays a pivotal role in development and tissue homeostasis in multicellular organisms. Clustering of Bak proteins on the mitochondrial outer membrane is responsible for the induction of… (More)
An ultra-compact 3 × 12 mm<sup>2</sup> DPOH on a 1.5%-Δ silica-based PLC employing a novel coupler is reported. The excess loss is <;2 dB and the CMRR is <;-27 dBe over the C- and L-bands.
We demonstrate a low power consumption differential quadrature phase-shift keying (DQPSK) demodulator using silica-based planar lightwave circuit (PLC) technology. A reduction of the power… (More)
We present an DQPSK demodulator with a silica-based PLC type MZI, where a half-wave plate is asymmetrically allocated to reduce polarization dependent frequency shifts, and demonstrate an error-free… (More)
