Abstract
According to the invention there is provided a tunable laser system for use in an optical communication system, said tunable laser system comprising a multi-section laser separated by at least two slots to define a plurality of sections, each section adapted to provide an optical gain. Each section comprises a separate control means to provide an adjustable optical gain in each section. The tunable laser system and method of the present invention provides a wide tuning range, narrow linewidth and fast switching times.
Claims14
A tunable laser system for use in an optical communication system, said tunable laser system comprising:
- a multi-section laser configured with at least two slots to define a plurality of sections, each section adapted to provide an optical gain;
- and
- each section comprises a separate control mechanism to provide an adjustable optical gain in each section.
A tunable laser system for use in an optical communication system, said tunable laser system comprising:
- a multi-section laser configured with at least two slots to define a plurality of sections;
- at least one first section comprising a separate control mechanism to provide an adjustable optical gain in the first section;
- and
- at least one second section comprising an intermixed section and a separate control mechanism adapted to shift a bandgap in said second section.
A transmitter for use in an optical network comprising:
- a tunable laser system having a multi-section laser separated by at least two slots to define a plurality of sections, each section adapted to provide an optical gain;
