Paper Abstract

Static and dynamic characteristics of three different laser structures, by using the same active structure, have been investigated: (1) conventional BRS (Buried Ridge Structure), (2) p-n multi-junctions (MJ) blocking layers and (3) Fe-doped semi-insulating (SI) InP blocking layer. Good blocking properties in MJ and SI laser structures have been showed by measuring the DC leakage current and the linearity of the power versus current (P-I) curve, also at high operating temperature; SI laser, respect to BRS and MJ structures, has shown a large reduction in parasitic capacitance and a considerable improvement in modulation bandwidth, limited only by dynamic characteristic of active region.
