“…There were four emission bands located at about 485, 550, 590, and 620 nm, which were ascribed to the transitions of 5 D 4 → 7 F j , respectively. 21,22) These results are similar to these in other previous reports, such as Refs. 2, 6, and 7.…”

In this paper, high-efficiency green upconversion luminescence from a terbium (Tb3+)-doped germanate glass is reported. The upconversion luminescence involved a simultaneous three-photon absorption process. Compared with an emission spectrum excited at 377 nm, the upconversion luminescence bands of Tb3+ pumped by an fs laser showed a slight red-shift. This was ascribed to the redistribution of glass composition when the glass sample was exposed to the high-intensity laser, which results in the aggregation of Tb3+ around the laser-exposed focal region, which in turn results in the slight red-shift of luminescence. The upconversion luminescence intensities at 540, 590, and 620 nm strongly depended on the polarization angle of the femtosecond laser, which was ascribed to the different transmittances of a half-wavelength plate at different polarization angles, which results in the regularity change in fs laser power.

On-chip optical interconnects heterogeneously integrated on silicon wafers by transfer-print technology are presented for the first time. Thin (<5 μm), micron sized light-emitting diodes (LEDs) and photo diodes (PDs) are prefabricated and transfer-printed to silicon wafer with polymer waveguides built between them. Data transmission with total power consumption as low as 1 mW, signal to noise ratio of >250 and current transfer ratio of 0.1% in a compact volume of <0.0004 mm 3 are demonstrated. Experiment shows that the polymer waveguide between the LED and PD plays a key role in enhancing the data transmission efficiency. Reciprocal performance for bidirectional transmission is also achieved. The results show the potential for cost-effective and low profile form-factor on-chip opto-isolators.

“…Magneto-optical glass is a good candidate for application for multiple components (optical isolators, circulators, fiber switch, and so on) in fiber communication systems and high-power laser systems, owing to its outstanding optical performances. 1,2 The laser with smaller divergence angle is more suitable for long distance transmission in the satellite laser communication system (SLCS). Although there are many researches on the improvement of laser performance parameters recently, these confine to the adjustment of auxiliary optical devices in the laser structure.…”

The bunching and deflection characteristics of low-power laser beam were investigated under electromagnetic field. On the basis of the Faraday effect, the cylindrical electromagnetic cavity was designed and implemented in the experiments. Several types of the magneto-optical elements were placed in the electromagnetic cavity individually. In the test of the deflection characteristics of low-power laser, the rotating angle, the polarization plane of linearly polarized light which passed through electromagnetic cavity, was measured by polarization extinction. We focus on the relation between the coil current and the rotating angle. The experimental data show that when the coil current varies in the range of 0–5 A, the rotating angles changed from 0° to 24.1°. Then, a fitting formula about the coil current and the rotating angle was obtained from the experimental data using the least square algorithm. The analysis shows that the rotating angle is proportional to the excitation current and the correlation coefficient is more than 0.9995. In order to study the beam bunching characteristics of low-power laser, the area of the laser facula was measured after the low-power laser passed through the electromagnetic cavity. The experiment data show that the laser facula area changes in a small range and the experimental data meet 3σ criteria.
