Continuous-wave phase-matched molecular optical modulator
In optical modulation, the highest available modulation rate is basically limited to the GHz frequency range at best. This is because optical modulation is often performed using electro-optic or acousto-optic effects that require application of an external signal to solid-state nonlinear optical materials. Here we describe optical modulation of continuous-wave radiation at frequencies exceeding...
متن کامل17 THz Continuous - Wave Optical Modulator
We use coherently rotating hydrogen molecules and demonstrate a continuous-wave (CW) optical modulator at a frequency of 17.6 THz that can modulate any laser within the optical region of the spectrum. The molecules are prepared in a coherent state by using two intense laser beams spaced by the Raman transition frequency inside a high finesse cavity. PACS numbers: 42.65.Dr, 42.65.Re, 42.50.Gy
متن کاملEffect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملDispersion Evaluation In Optical Wave Guides
One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
