A waveguide photodetector (WGPD) is very attractive device for future optical communication systems and optoelectronic integrated circuits (OEIC) because the wide bandwidth operation at higher quantum efficiencies can be obtained. Also, these devices have advantage of packaging technology, since waveguide structure, which is similar to laser structure, is suitable for planar OEIC. Furthermore, it can be operated under zero-bias and biased conditions. In this paper, the performance of zero-bias and biased pin waveguide photodetector is compared with respect to internal quantum efficiency and internal quantum efficiencies as high as 105% are achieved.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
