The characteristic deterioration of a titanium indiffused Y junction due to the photolithographic process constraint is simulated. It is found that with a slight increase in propagation loss, an improved design, which uses a rounded angle instead of a sharp one for the fabrication of the Y junction, can be created. © 1992 John Wiley & Sons, Inc.
