Integrated chip-scale Si3N4 wavemeter with narrow free spectral range and high stability
نویسندگان
چکیده
We designed, fabricated, and characterized an integrated chip-scale wavemeter based on an unbalanced Mach– Zehnder interferometer with 300 MHz free spectral range. The wavemeter is realized in the Si3N4 platform, allowing for low loss with ∼62 cm of on-chip delay. We also integrated an optical hybrid to provide phase information. The main benefit of a fully integrated wavemeter, beside its small dimensions, is increased robustness to vibrations and temperature variations and much improved stability over fiber-based solutions. © 2016 Optical Society of America

On-chip visible-to-infrared supercontinuum generation with more than 495 THz spectral bandwidth.
We report ultra-broadband supercontinuum generation in high-confinement Si3N4 integrated optical waveguides. The spectrum extends through the visible (from 470 nm) to the infrared spectral range (2130 nm) comprising a spectral bandwidth wider than 495 THz, which is the widest supercontinuum spectrum generated on a chip.
متن کاملHigh Extinction Ratio Widely Tunable Low-Loss Integrated Si3N4 Third-Order Filter
We demonstrate an integrated continuously tunable third-order ring filter with a measured extinction ratio of 80dB, a 100x improvement over previously demonstrated integrated 3 or 6 order filters. Using integrated thermal tuning elements, the filter can be tuned over 100% of its 48 GHz free spectral range with 1.3 dB insertion loss. The filters are fabricated on a wafer-scale foundry compatible...
متن کاملDirect measurement of the on-chip insertion loss of high finesse microring resonators in Si3N4-SiO2 technology
Microring resonators show the possibility for designing Very Large Scale Integrated (VLSI) photonic circuits by cascading them. In order to realize the devices, the on-chip insertion loss becomes an important parameter. The direct measurement of the on-chip insertion loss of a high finesse microring resonator will be presented. Its value (0.1 ± 0.1) dB is low, in agreement with calculations.
متن کاملDevelopment of high-resolution arrayed waveguide grating spectrometers for astronomical applications: first results
Astrophotonics is the next-generation approach that provides the means to miniaturize near-infrared (NIR) spectrometers for upcoming large telescopes and make them more robust and inexpensive. The target requirements for our spectrograph are: a resolving power of ⇠3000, wide spectral range (J and H bands), free spectral range of about 30 nm, high on-chip throughput of about 80% (-1dB) and low c...
متن کاملA Fully Integrated Range-Finder Based on the Line-Stripe Method
In this paper, an imaging chip for acquiring range information using by 0.35 μm CMOS technology and 5V power supply has been described. The system can extract range information without any mechanical movement and all the signal processing is done on the chip. All of the image sensors and mixed-signal processors are integrated in the chip. The design range is 1.5m-10m with 18 scales.
