Download or read book Electroabsorption Mechanisms in Germanium Quantum Well Material written by Rebecca Kayla Schaevitz and published by Stanford University. This book was released on 2011 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: One possible solution to make viable optoelectronic modulators that meet strict targets down to the scale of on-chip communication is to use germanium-rich materials. Ge/SiGe quantum wells grown on silicon substrates provide the strongest mechanism, the quantum-confined Stark effect (QCSE), and thereby can meet the strictest requirements for optical interconnects, including CMOS-compatibility. Using such a strong effect, Ge-based modulators can be ultra-compact, ultralow-power, large bandwidth and high-speed, making them a strong contender for the future of optoelectronic device integration to solve the bottleneck problem. In this thesis, we will discuss the physical properties of the Ge and SiGe material system then present designs of optoelectronic modulators at the important 1310 nm and 1550 nm communication wavelengths using a program we developed called the Simple Quantum Well Electroabsorption Calculator (SQWEAC). SQWEAC takes the important physical mechanisms present, such as QCSE and indirect absorption, to predict the electroabsorption profile of Ge-based quantum wells. QCSE was experimentally determined on a wide range of samples to show the predictive powers of SQWEAC. Additionally, indirect absorption was also experimentally determined to optimize the physical model for these Ge quantum well devices. In being able to design both 1310 nm and 1550 nm devices using this Ge material system, we provide a platform for designing optoelectronic devices that are Si CMOS compatible and operate over a wide range of wavelengths. These modulators have the capability of providing the large density of information at very low energies per bit required for future interconnect technologies.

Download or read book Selected Topics in Inorganic Chemistry Part II written by Dr. A. AHMED RAZA & Dr. SEENU RAVI and published by Shashwat Publication. This book was released on 2024-09-05 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for the postgraduate students of chemistry aspiring to crack competitive examinations such as CSIR-NET, GATE, SLET/SET and PhD entrance examinations. Presently, admission to PhD programs in premier institutions like IITs, NITs, CSIR laboratories, central universities and state universities is based on either NET/GATE certificate or PhD entrance examinations. Further, the minimum eligibility criteria laid by UGC for the direct recruitment of Assistant Professors in the higher educational institutions is a postgraduate degree with NET/SLET/SET certificate. Thus, the students are bound to pass these examinations to pursue a bright career either in research or in academic teaching. The cut off for qualifying these exams is 40 to 50%. However, the qualifying percentage of the candidates appearing for these examinations is around 5% only. Therefore, an attempt has been made by authors to develop study material pertaining to the syllabus of these exams along with the solved problems from the previous year question papers which will guide the students to qualify easily.
Download or read book Towards the First Silicon Laser written by Lorenzo Pavesi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon, the leading material in microelectronics during the last four decades, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated to date. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. In the recent past, many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are abundantly illustrated in the present book.
