This paper focuses on fabrication and assembly processes of modular and hybrid microoptical systems in use in sensor and telecommunication fields. These microoptical systems are made by a huge variety of processes, which are commonly known as microsystem technology. Nevertheless, quite a lot of them are based on the LIGA process, since LIGA is an "assembly friendly" technology.Modular microoptical systems typically comprise several functions incorporating mechanical or electromechanical components beside the optical elements. The assembly of the diverse submounts and components is performed actively as well as passively. In many cases, all of these functions can be combined on one single chip. In several cases, however, a pair of chips, which is assembled in a flip-chip like way, is used.The framework of the paper leads to a definition of the terminus "modular microoptical system" and argues for the advantages of such a modular design approach. It closes with some remarks on automatic assembly strategies.

“…Although there are plenty of 1D connector components on the market, existing fabrication techniques like excimer laser photoablation [33], silicon micro-machining [34] and deep lithography with x-rays [35] have not shown to be able to create 2D connectors for single mode fibres that can be mass-fabricated with the required high accuracies and at low cost.…”

In this work a research on pulsed electrochemical micromachining of Stainless Steel is presented. A suitable equipment to study the process is described as well as a fitting procedure to machine and measure the variables involved. A tool of Tungsten with a tip of about 5 mm diameter sunk in an electrolyte of NaNO3 is used for the process. The pulse on-time must be maintained in the order of ns to achieve a good current confinement, since the tool is active. Some experiments were made to assess the most important variables of the process, as current confinement, surface roughness, material removal rate and efficiency. It is observed that the current confinement get worse when the pulse on-time increases, as well as surface roughness. The material removal rate and the efficiency increase with the voltage amplitude and the pulse on-time. The voltage amplitude must be higher than 12 V so that the phenomenon of passivation disappears. There is a compromise in the choice of the variables, so a suitable combination of parameters is determined so that a good material removal rate with an acceptable result is achieved.
