Abstract
Apparatus and methods are provided for measuring a selected optical behavior of a tunable opto-electric device by using the electrical characteristics of the opto-electronic device. The benefit of the present invention is the elimination or reduction in complexity of optical wavelength reference hardware that is currently required for wavelength referencing and locking. Accordingly, the present invention reduces the cost and complexity of the optical packaging of tunable opto-electronic telecommunication components. Furthermore, the present invention also significantly simplifies optical and electronic design of system level products with tunable opto-electronic devices.
