We fabricated the photonic metamaterial crystal structure and evaluate their photonic properties. The metamaterial photonic crystals studied here were periodic structures with two types of surface areas where two different dimension sprit ring resonators (SRR) were fabricated on each area. These two different SRR were designed to possess near but different resonance frequencies. We performed Fraunhofer...
A 10-Gb/s Mach-Zehnder modulator is monolithically integrated with a tunable laser source based on a 2-ring loop-filter with a small device dimension (2.5 × 0.9 mm2). Sufficient static extinction ratio of 16.5 dB was obtained both at 1573.92 and 1595.50 nm.
We propose a widely tunable and low insertion loss loop filter incorporating two ring resonators and an asymmetric Mach-Zehnder interferometer. A semiconductor optical amplifier, phase control section, and loop filter are monolithically integrated on one chip in the InP-InGaAsP material system. The tuning range of 39 nm with side-mode suppression ratio of over 30 dB was demonstrated. The maximum of...
A compact 10 Gb/s full C-band tunable transmitter module of external cavity tunable light source with monolithically integrated Mach-Zehnder modulator was developed. Penalty free 10 Gb/s - 80 km transmission over full C-band has been successively achieved.
A monolithically integrated wavelength-tunable laser diode based on a novel loop-filter that consists of two ring resonators and an asymmetric Mach-Zehnder Interferometer (AMZI) is demonstrated with 39-nm tuning range over 30-dB SMSR.
We present a gap mirror based monolithic integration technology of functional sections on a gain chip for an external cavity wavelength tunable laser (ECTL). The effective reflectivity and coupling coefficient of the gap mirror can be controlled by changing gap length and gap angle. Utilizing this technique, we experimentally demonstrated full C-band ECTL with integrated variable optical attenuator...
