Abstract

Some effective method of localizing the waveguides striped structures is presented below. The possibility of such localization is particularly important then, when a preliminary estimation of the stripe waveguides is necessary in order to find out quickly the absence of any gaps and narrowings and the preservation of their shapes in the boundary regions. The observation is carried out with a microscope equiped with a source of coherent light. For the purpose of localizing the structures on the substrates polished one-sidedly, their observation is carried out under the condition of revealing the diffractional patterns. The visualization of the waveguides on the both-side polished substrates is obtained with the interference methods. Due to a good visualization of the waveguides, the common laborious technique of coupling the fiber waveguides as well as the hybrid set-up of electro-optical elements are both effectively improved.
