Abstract

Characterization of DWDM photonic integrated circuits presents many challenges and trade-offs. High channel numbers significantly increase the required time to screen and qualify devices at different stages within their production. The SurePath Monitor product requires accurate calibration of the absolute responsivity of each of its 43 100GHz-spaced channels, across the C-band (1525 to 1565nm), to meet its power monitoring accuracy specification of ±0.5dB. Further specifications such as input optical power range (0 to -40dBm) require photocurrent measurement capabilities ranging from mA down to sub-nA levels, whilst the high efficiency of the integrated demultiplexer filter requires large electrical dynamic range (>65dB). Characterization stations developed to ensure high throughput and low cost without sacrificing measurement accuracy and repeatability were based upon matrix-based measurement methodologies to ensure this balance is achieved.
