Optoelectronic devices, such as optical transmitters and optical
amplifiers, are provided. The optoelectronic devices are suitable for use
in connection with optical communications systems, and related components
and devices, such as may be used in the transmission, reception and
processing of data and other information. The optoelectronic devices are
implemented as various types of semiconductors. The form, structure,
properties and functionality of a particular optoelectronic semiconductor
device are determined with reference to the application(s) in connection
with which the optoelectronic device is to be employed.
