2. Overview Objective/Scope Approach Major Accomplishment
Demonstrated directly modulated OEIC-WC with monitoring capabilities
Approach
Photodiode directly connected to SGDBR gain section
Major Accomplishment
Designed and fabricated 1st run of 1st gen OEIC-WC
Begun initial testing/characterization
Main Issues/Problems/Limitations
Contacts, parasitics in test setup limit what …
Improve monitor design
Improve preamp-SOA design, SGDBR tuning, power output
Extinction ratio and chirp

3. Current Status and Future Directions
Devices to be AR coated, mounted on heat-sink, ground connection repaired
High speed measurements possible
Likely to satisfy Phase I milestones(?)
Second mask spin will address several aspects
Improved monitor/bias connection
Improved SOA/detector design
Improved SGDBR design
Inclusion of multiple-active region embodiment
Investigation of saturable absorbers for improved extinction in digital applications
