1High-performance modified uni-traveling carrier photodiode integrated on a thin-film lithium niobate platform显示文摘Lithium niobate on insulator(LNOI)has become an intriguing platform for integrated photonics for applications in communications,microwave photonics,and computing.Whereas,integrated devices including modulators,resonators,and lasers with high performance have been recently realized on the LNOI platform,high-speed photodetectors,an essential building block in photonic integrated circuits,have not been demonstrated on LNOI yet.Here,we demonstrate for the first time,heterogeneously integrated modified uni-traveling carrier photodiodes on LNOI with a record-high bandwidth of 80 GHz and a responsivity of 0.6 A/W at a 1550-nm wavelength.The photodiodes are based on an n-down In GaAs/InP epitaxial layer structure that was optimized for high carrier transit time-limited bandwidth.Photodiode integration was achieved using a scalable wafer die bonding approach that is fully compatible with the LNOI platform.XIANGWEN GUO LINBO SHAO LINGYAN HE KEVIN LUKE JESSE MORGAN KEYE SUN JUNYI GAO TA-CHING TZU YANG SHEN DEKANG CHEN BINGTIAN GUO FENGXIN YU QIANHUAN YU MASOUD JAFARI MARKO LONčAR MIAN ZHANG ANDREAS BELING 2022Photonics Research2022,10,6:2
2New perspectives on the prevention of myopia显示文摘The high prevalence of myopia and its public health and clinical consequences make prevention of myopia a top priority.Traditional approaches to prevention have been based on reducing accommodative load,and have generally been unsuccessful.Only treatment with atropine eye-drops has produced clinically significant effects,.which are however of limited duration and suffer from potential side-effects.In addition,based on animal experimentation,.it is now clear that atropine blocks eye growth by mechanisms which do not involve accommodation..More generally,.experimentation on animal models of myopia has shown that accommodation is not im-portant for the control of eye growth,whereas exposure to hyperopic (growth-promoting) and myopic (growth-inhibit-ing) defocus is more important.Recent epidemiological evi-dence has also questioned the importance of near work,al-though education is clearly important.This suggests a preven-tive approach based on deliberately increasing the amount of myopic defocus a child is exposed to may be successful.There is also convincing evidence that children who spend more time outside are less likely to become myopic,which also suggests a quite non-invasive approach to prevention.These new directions need to be pursued.Fan Xiang MD Ian G.
