The invention relates to a test arrangement comprising a waveguide, a first signal reflecting device and a second signal reflecting device. The first signal reflecting device is configured to reflect an electromagnetic signal traveling along the waveguide from the second signal reflecting device back towards the second reflecting device and to allow, at least during a time period, an electromagnetic signal traveling along the waveguide from the second signal reflecting device towards the first signal reflecting device to pass the first signal reflecting device.

Lift-off processing for formation of isolation regions in laser diode structures
A method of fabricating a laser diode structure is provided where a photolithographic process is utilized to form at least a portion of an axially extending waveguide structure such that a patterned photoresist remnant resides over the axially extending waveguide structure following the photolithographic process. A patterned isolated opening and a lift-off photoresist portion are formed in the patterned photoresist remnant by subjecting the patterned photoresist remnant to an additional photolithographic process such that the lift-off photoresist portion remains in residence over the axially extending waveguide structure following the additional photolithographic process.
