We experimentally succeeded fabrication and WGM lasing of inorganic microdisks by the ink-jet printing method. This silica-based microdisk cavity is the first demonstration in ordinary pressure and temperature among inorganic microdisks.
Whispering Gallery Modes (WGMs) resonator based biosensors have received much attention due to the advantages of small volume, high sensitivity and label-free. Such sensors can be assigned into passive resonator sensor [1] and active resonator sensor. Different with passive resonator sensor, active resonator based sensor [2] is potential because there are (i) no need an expensive tuneable laser as...
Microdisk cavities are a kind of whispering gallery mode (WGM) resonators, which are continually studied owing to their high quality factor (Q factor) and small mode volume. These microdisks were previously fabricated using a subtractive method [1, 2] such as photolithography method. These subtractive methods are suitable for the mass-produced industrial structure due to an ability of the mass fabrication...
We report the thermal design of 28-Gb/s × 24-channel CDR-integrated VCSEL-based transceiver optical module for high density optical interconnects. The transceiver module realizes a very high data rate density of 1346 Gb/s/inch2 at a total power consumption of 9.1 W. A unique design of this optical module realizes to use the whole top surface for thermal dissipation. We performed thermal simulations...
We demonstrate a very high density 28-Gb/s × 24-channel CDR-integrated VCSEL-based optical transceiver module. The optical module achieves a very high data rate density of 1344 Gb/s/inch2 (2.08 Gb/s/mm2). An optical link employing the optical module achieved a jitter margin of 0.48 U.I. at a BER of 10−12 at case temperatures ranging from 31 °C to 70 °C with a very low link power of 13.5 mW/channel/Gb/s.
To realize simple and low-cost VCSEL-based parallel-optical modules mounted onto a polymer-waveguide-embedded PCB in high density, we propose a new mounting technology using a guide pin-assisted optical coupling stabilization during a Sn-Ag-Cu solder -- reflow process. The guide holes of the 12-channel optical module and the guide pins of optical PCB are precisely shaped by a high-precision machining...
We report a solderable 4-channel VCSEL-based optical transceiver module perfect for high-volume production of QSFP AOCs. The 4-channel module can be simply mounted on a PCB together with other electronics components through a solder reflow process. We fabricated a PCBA in compliance with the standard of QSFP edge connector. The PCBA has an MCU written with a firmware included with a look-up table...
We introduce solder reflow-capable high-density parallel-optical modules for >100 Gb/s optical interconnects. Polymer-waveguide-coupled parallel-optical modules are also introduced with a unique mounting technology. 1060-nm 28-Gb/s InGaAs/GaAs VCSEL realizes a good signal quality at high temperature and error free for MMF transmission beyond 500m.
We demonstrate a novel architecture of mounting parallel-optical modules (POMs) onto an optical printed circuit board (PCB) through Sn-Ag-Cu-solder reflow process where precisely positioned stud-pins on optical PCB and guide holes formed on POMs were mated to maintain good optical coupling. We confirmed that fabricated 14-Gb/s × 12-channel POMs achieved a good transmission performance on a test environment...
