The packaging of photonic integrated circuits is necessary for taking them out of research laboratories into real implementation in the information and communication technology applications. Telecom optical fibers are still being the best transmission medium of digital data and analogue signals for long distance applications. The effective coupling of optical radiation between telecom optical fiber with ten microns core dimension and photonic integrated circuits optical waveguides with submicron dimensions are necessary. To address these challenges, we present our concept of photonics integrated circuit packaging with radio frequency, direct current and fiber array ports with automated active alignment system.

Book of abstracts. 2nd International Conference on Photonics Research. November 4-9 2019. Antalya, Turkey N2 - Optical splitters are passive optical components, which have found applications in a wide range of telecom, sensing, medical and many other scientific areas. Low-index contrast optical splitters (Silica-on-Silicon (SoS) based waveguide devices) feature many advantages such as low fiber coupling losses and low propagation losses. They are considered an attractive DWDM solution in the telecommunication for all optical signal processing in optical communication systems. Nowadays the steadily increasing data volume in communication networks is driven by a rapid proliferation of home-based and business computers, storage capacities, processing capabilities and the extensive availability of Internet. The challenge is to transfer high data volumes in short periods of time over high distances as lossless as possible. The task of the optical splitters in Fiber-to-the-x (FTTx) network is to split one optical signal in many identical signals bringing for example the same TV signal in different households. Of course, the more buildings can be served by one optical splitter the lower are the installation costs. High-index contrast optical splitters (such as silicon, silicon nitride or polymer based waveguide devices) feature much smaller waveguide size compared to low index contrast splitters. Such compact devices can easily be implemented on-chip and have already been used in the development of optical sensors, devices for DNA diagnostics and for infrared spectroscopy. We will present the latest achievements in the design of two mostly used optical splitters (MMI and Y-branch) and discuss their advantages and disadvantages. Finally, some applications of the splitters developed in the frame of various projects will be presented. This work was carried out in the framework of the project PHOCOP (no. SK-AT-2017-0013) and NAMOPRISIN (no. SK-AT-2017-0005) from the Slovak research and development agency of the Ministry of Education, Science, Research and Sport of the Slovak Republic and SK 16/2018 and 15/2018 from OeAD-GmbH.

Dubai, United Arab Emirates. 15 - 17 April 2019 N2 - Introducing 3D sub-micrometer technologies based on polymers opened new possibilities of design and fabrication of photonic devices and components in 3D arrangement. 3D laser lithography is direct writing process based on two photon polymerization exhibiting high accuracy and versatility, where numerous resists and even polymer ceramic mixtures can be used. We present design and simulation of polymer based photonic components with a focus on arrayed waveguide gratings (AWG) based on optical multiplexers/demultiplexers and optical splitters. All optical components were designed for 1550 nm operating wavelength, applying two commercial photonics tools. This study creates a basis for the design of optical components in 3D arrangement, which will be fabricated by 3D laser lithography.

The paper deals with the design and simulation of fiber to SiN chip butt coupler with single step fabrication process without thickness tapering. Coupler is designed for 850 nm band for coupling between strip 0.25 μm × 1.00 μm waveguide and Nufern's 780-OCT single mode optical fiber with core diameter 4.4 μm. The coupling losses simulation results of the two simulation methods finite-difference beam propagation techniques and eigenmode expansion method are compared.

Strbske Pleso, High Tatras, Slovakia. June 24 - 27, 2019 N2 - We present design and simulation of 16-channel, 100-GHz silicon nitride based AWG using BeamPROP simulation engine of RSoft photonic tool. The AWG was designed for TM-polarized light with central wavelength of 850 nm. The input design parameters were calculated applying AWG-Parameters tool. For this purpose, we created a ridge waveguide structure, used in the design of the AWG layout, and performed FEM simulation. The output of the BPM simulation of AWG structure are the transmission characteristics, which was used to calculate transmission parameters defining optical properties of simulated AWG. The achieved simulation results are in a good agreement with the design.
