Abstract
Both electronics and optoelectronics are essentially based on de Broglie wave-particle duality which has played its role as the micro-particle fundamentals including the relation between particle energy and wave frequency and that between particle momentum and wavelength. However, the frequency-determination energy in the first relation has usually been misunderstood as the rest-energy included total particle energy and the wavelength in the second relation has been mistaken as a quantity only related to the momentum. Here presented are the modified ones featuring the rest-energy excluded frequency-determination energy and the potential-energy-affected wavelength (an effective momentum p_eff =(1+Q_uU/E_k)p is introduced) as well as the consequentially modified Schrödinger equation and Dirac equation respectively as follows：

And, in the case of zero potential energy, the latter one becomes

These modifications might lead to fascinate stories of the quantum-mechanics theory and various relevant technologies, especially in the area of electronics and optoelectronics.

Xiaomin Ren, IET Fellow, COS Fellow, CIE Fellow, Professor of Beijing University of Posts and Telecommunications (BUPT), Chief Scientist of the State Key Laboratory of Information Photonics and Optical Communications of China (SKL-IPOC), Vice President of Chinese Optical Society (COS). He had also been a Vice President of BUPT (1996-2017), the Director of SKL-IPOC (2003-2023) and the Chairman of ACP Conference Steering Committee (2015-2023). He worked as a Senior Visiting Scholar in Centro Studi E Laboratori Telecomunicazioni, Turin, Italy, and then as a Visiting Senior Research Fellow in the Microelectronics Research Center, University of Texas at Austin, USA, during 1994 to 1996. He had been awarded with the title of Outstanding Young Scientist of China by NNSFC (1996). He had been a Vice Head of the Optoelectronic Expert Group under the National 863 Program for many early years and the Chief Scientist of the relevant research projects of the National 973 Program twice from 2003 to 2014. He has worked on information optoelectronic technologies and nanoheterostructure physics, mainly including semiconductor lasers, photodetectors, silicon-based III-V optoelectronic integration, novel low-dimensional heterostrucutures and devices, photonic crystal fibers, etc. He has also worked on fundamental physics since 2012 and proposed the concept of energy-level divergence, the theory of fractional (or continuous real-number) dimensionality electron-states architecture in semiconductors, the Bivergentum Theory going to unify the classical and quantum mechanics together and extend the Einstein's high speed special theory of relativity to a quite new one, i.e. the full-velocity-scope special theory of relativity. He advocates that quantum mechanics must go back to Logicism (in contrast with Instrumentalism) and believes that there does exist an amazing super-low speed 'world'.

This report focuses on the integration of devices or components using quartz fiber as the substrate material, and discusses how to miniaturize and integrate various optical device or elements into a single fiber. The construction of functional optical devices, or the realization of optical component integration on the fiber through the combination of several single-function optical devices are systematically explored. The primary concepts and key technologies for the integration of optical devices and components in optical fibers are systematically summarized. The main functionalities and applications of such integrated devices and components in optical fiber communication and sensing are comprehensively reviewed. Finally, the potential application prospects of this technique in the field of minimally invasive interventional medicine in the future are elaborated.
