概要

• 論文の詳細を見る

• A reflectivity design of an integrated optical head is presented based on basic design quantities such as laser diode efficiency, write-erase power margin, phase-change medium sensitivity, and permissible read power. We obtain a reflectivity of R_1≒0.7 for the laser diode facet that faces the photodetector, R_2=0.01 for the same diode facet that faces the medium, 0.21≥R^h_3≥0.14 for the medium, and a reflectivity difference between the two medium reflectivity states of R^h_3-R^l_3≒0.05.
