| 1 | Cu溅射诱导增强量子阱混杂实验研究显示文摘在InP基异质结InGaAsP多量子阱(MQW)结构上溅射Cu/SiO2复合层,开展了量子阱混杂(QWI)材料的实验研究。经快速退火(RTA),实现了比常规无杂质空位扩散(IFVD)方法更大的带隙波长蓝移量。在750℃、200s的退火条件下,获得最大172nm的波长蓝移;通过改变退火条件,可实现不同程度的蓝移,满足光子集成技术中不同器件对带隙波长的需求。为了验证其用于光子集成领域的可行性,利用混杂技术分别制备了宽条激光器和单片集成电吸收调制激光器(EML)。在675℃退火温度,80s、120s和200s的退火时间下分别实现了61、81和98nm的波长蓝移;并且,相应的宽条激光器的电激射光(EL)谱偏调量与其材料的光致荧光(PL)谱偏调量基本一致。在675℃、120s退火条件下,制备的EML集成器件中,电吸收调制器(EAM)和分布反馈(DFB)激光器区的蓝移量分别83nm和23.7nm,相对带隙差为59.3nm。EML集成器件在激光器注入电流为100mA、调制器零偏压时出光功率达到9.6mW;EAM施加-5V反向偏压时静态消光比达16.4dB。 | 崔晓 张灿 梁松 Hou Lianping 朱洪亮 | 2014 | 光电子.激光2014，25，7： | 1 |
| 2 | Regrowth-free AlGaInAs MQW polarization controller integrated with a sidewall grating DFB laser显示文摘Polarization control is at the heart of high-capacity data optical communication systems,such as polarizationdivision multiplexers and Stokes vector modulation transmitters.Despite passive polarization control being mature,the realization of monolithically integrated polarization controllers and single longitudinal mode light sources,such as distributed-feedback(DFB)lasers,is of importance.In this research,we report an AlGaInAs multiple-quantum-well photonic integrated circuit device which can control the state of polarization of the output light source,consisting of a polarization mode converter(PMC),a differential phase shifter(DPS),and a sidewall grating DFB laser.We demonstrate an asymmetrical stepped-height ridge waveguide PMC to realize TE to TM polarization conversion and a symmetrical straight waveguide DPS to enable polarization rotation from approximately counterclockwise circular polarization to linear polarization.Based on the identical epitaxial layer scheme,all the PMC,DPS,and DFB lasers can be integrated monolithically using only a single step of metalorganic vapor-phase epitaxy and two steps of III-V material dry etching.For the DFB-PMC device,a high TE to TM polarization conversion efficiency(98.4%)over a wide range of DFB injection currents is reported at 1555 nm wavelength.For the DFB-PMC-DPS device,a nearly 60°rotation of the Stokes vector on the Poincarésphere was obtained with a range of bias voltage from 0 to-3.0 V at a laser drive current of 170 mA. | XIAO SUN SONG LIANG WEIQING CHENG SHENGWEI YE YIMING SUN YONGGUANG HUANG RUIKANG ZHANG JICHUAN XIONG XUEFENG LIU JOHN HMARSH LIANPING HOU | 2023 | Photonics Research2023，11，4： | 0 |
| 3 | Monolithic DWDM source with precise channel spacing显示文摘We report a low-cost manufacturing approach for fabricating monolithic multi-wavelength sources for dense wavelength division multiplexing(DWDM)systems that offers high yield and eliminates crystal regrowth and selective area epitaxy steps that are essential in traditional fabrication methods.The source integrates an array of distributed feedback(DFB)lasers with a passive coupler and semiconductor optical amplifier(SOA).Ridge waveguide lasers with sampled Bragg side wall gratings have been integrated using quantum well intermixing to achieve a fully functional four-channel DWDM source with 0.8 nm wavelength spacing and residual errors<0.13 nm.The output power from the SOA is>10 mW per channel making the source suitable for use in passive optical networks(PONs).We have also investigated using multisection phase-shifted sampled gratings to both increase the effective grating coupling coefficient and precisely control the channel lasing wavelength spacing.An 8-channel DFB laser array with 100 GHz channel spacing was demonstrated using a sampled grating with twoπ-phase-shifted sections in each sampling period.The entire array was fabricated by only a single step of electron beam lithography. | Lianping Hou Song Tang John H.Marsh | 2021 | Journal of Semiconductors2021，42，4： | 0 |
