A new theoretical framework to describe the experimental advances in electro-optic detection of broadband quantum states, specifically vacuum, is devised. Electro-optic sampling a technique ultrafast photonics which, when transferred into domain, can be utilized resolve properties sampled state via its interaction with strong coherent probe pulse at timescales. By making use fundamental concept...
The integration of low-dimensional materials with optical waveguides presents promising opportunities for enhancing light manipulation in passive photonic circuits. In this study, we investigate the potential aerosol-synthesized single-walled carbon nanotube (SWCNT) films silicon nitride circuits as a basis developing integrated optics devices. Specifically, by measuring response SWCNT-covered ...
The power of a group DWDM signal increases nonlinear interference in the optical path, especially value FWM. These interfering factors degrade transmission quality and can completely disable WDM system. Therefore, when designing system, it is necessary to optimize transmitted minimize probability error channel. article presents research results analysis affecting fiber-optic communication syste...
morning glory syndrome (mgs) is a rare congenital optic disc anomaly characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. the main ophthalomoscopic feature of the mgs is enlarged optic disc with a funnel shaped scleral defect; elevated peripapillary chorioretinal pigmentation; and pale fluffy tissue of glial hyperplasia overlying the optic d...
purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...
Active manipulation of light in optical fibres has been extensively studied with great interest because of its compatibility with diverse fibre-optic systems. While graphene exhibits a strong electro-optic effect originating from its gapless Dirac-fermionic band structure, electric control of all-fibre graphene devices remains still highly challenging. Here we report electrically manipulable in...
