Publikováno v: Canadian Journal of Physics. 70:914-920

InP–InGaAs cleaved-cavity lasers are routinely used in long-wavelength optical transmission systems, packaged with a discrete pin photodiode back-facet monitor used to provide feedback to control the laser output power. This conventionally requires

Publikováno v: Applied Physics Letters. 62:222-224

A method for producing durable fused silica self‐interference grating photomasks is described. These masks allow repeated printing of both uniform and phase adjusted gratings. Periods as fine as 200 nm have been demonstrated. The fabrication of the

Publikováno v: SPIE Proceedings.

Application of semiconductor lasers in fiber-in-the-loop systems, where device temperatures would not be controlled and might vary from -40 degree(s)C to 85 degree(s)C, has brought new challenges in laser reliability requirements. Also, lifetime asse

Although surface-normal emission from a laser using a one-dimensional second-order grating has been published for some time [1], it is only in the last few years that the theory of circular (i.e. two-dimensional) gratings has been considered theoreti
