This paper present a novel idea of integrating a photodetector and a light emitting diode (LED) for wavelength conversion. The detector of interest here responds in the 1.5 micrometers wavelength region and LED emits in the near infrared (e.g., 800 - 900 nm). A proof-of-the- concept experiment has been conducted and presented here. The eventual application is to use this device in a focal plane imaging format for up-converting a 1.5 micrometers image to the near infrared then captured by a Si CCD camera.
