We demonstrate record performance heterogeneously integrated telecom wavelength and datacom wavelength lasers, processed simultaneously on the same wafer. Tunable lasers for telecom applications and uncooled 2x8 WDM laser arrays for datacom applications are presented.
Communications interconnects and networks will continue to play a large role in contributing to the global carbon footprint, especially in data center and cloud-computing applications exponential growth in capacity. Key to maximizing the benefits of photonics technology is highly functional, lower power, and large-scale photonics integration. In this paper, we report on the latest advances in the...
As the component count rises in photonic systems, photonic integration becomes increasingly attractive from a cost, power consumption, and footprint perspective due ability to reduce the on-chip to off-chip interfaces and simplify packaging. Although photonic integration has been investigated in many forms over the last decade, the incompatibility of passive and active devices in standard integration...
Flexible composite pre-cladding of tungsten carbide, nickel,chromium (WC-Ni-Cr) are shaped with mixer and roller and then be sticked on the Q235 steel substrate. Finally, WC-Ni-Cr composite cladding is fabricated by infiltration brazed technology. Several factors which would affect the process of infiltration brazed are analyzed. BNi-2 and BNi-7 are appropriate brazing-solder for infiltration brazed...
Silicon based photonic integration technology has advanced significantly in the last several years and it is maturing to the point that it can bring unique opportunities for avionics systems to utilize photonics.
When production yields are random and orders need to be satisfied in full, several production runs may need to be initiated until an order is met. The universal objective function usually used in conjunction with this process is the minimization of expected costs. However, sometimes the manufacturer may want to consider a deviation from the dasiaoptimalpsila cost-minimizing process, if the risk of...
We present experimental and theoretical analysis for thermal impedance (ZT) in a hybrid silicon evanescent laser. For an 850 mum long Fabry-Perot, we observe ZT of 41.8degC/W experimentally and 43.5degC/W theoretically, which is in excellent agreement.
