Design of optical amplifier
Somora, Rastislav ; Číž, Radim (referee) ; Slavíček, Karel (advisor)
This Bachelor's thesis deals with design and construction of support circuits for a modern optical amplifier the SOA. In the first chapter, optical transmitting medium with its physical properties and types of used cabels is described. The overview includes a list of optical cables, their damping properties and parasitic effects which can occur durring comunication. Next chapter is focused on the optical signal sources used in modern data networks, describes their internal structure and physical essence. Third chapter is dedicated to designing the optical amplifier with the SOA circuit. It focuses on the right choice of parts, their arrangement and layout of the design. Last chapter deals with set up, calibration and control of the optical amplifier module.

Design of semiconductor optical amplifier
Somora, Rastislav ; Hanák, Pavel (referee) ; Slavíček, Karel (advisor)
Diploma thesis deals with the construction of a moder semiconductor optical amplifier SOA. In the first chapter optical comunication and the use of optical amplifiers is described. In the next chapter some types of optical fibers, their chemical composition and properties are described in detail. The third chapter overviews optical amplifiers, their use today, describes their advantages and disadvantages and their proper use in optical comunications. The fourth chapter describes the solution of the objective, the right layout of separate blocks and connections used in measurements. Fifth chapter describes used components, describes their basic parameters and proper use in circuit. The last chapter evaluates outputs of measurements and their impact on the objective.

Fiber-Coupled Fabry-Pérot Interferometric Sensor: Analysis And Modelling
Skalský, Michal
This paper presents a theoretical analysis of the Fabry-Pérot interferometric sensor utilizingan extrinsic fiber-optic cavity. Its behavior is modelled and simulated for various conditions,showing the key properties of the different sensor’s setups. The simple single-mode sensing tip andthe GRIN collimator are compared. Further, new kind of sensing head is proposed exhibiting aninverse reflectivity and enabling a theoretical resolution less than 1 pm.

Fabry-Perot displacement interferometry in air
Šmíd, Radek ; Durand, M. ; Wang, Y. ; Lawall, J.
In earlier work, we have demonstrated the use of Fabry-Perot interferometry to measure displacements of up to 50 mm with a fractional accuracy of 4 x 10-10 in vacuum. The initial work was done at a wavelength of 633 nm, and the more recent work was done at 1560 nm. We now seek to extend the approach to displacement measurements in air. A well-known approach to compensate for the refractive index of air without relying on independent measurements of the temperature and pressure is to use two wavelengths. In this work, we supplement our implementation at 1560 nm with an additional laser at 1064 nm in order to control for the dispersion of air.
