“…Although adjusting the orientation of the wave plate can also cause a relative shift in the spectral response, selecting a wave plate with the right thickness can give rise to a more controllable spectral response and allow for simpler packaging. The wave plate can also be properly designed to compensate the thermal drift of the isolator response [10].…”

“…The ambiguity among different channels can be resolved from a channel-dependent characteristic of an optoelectronic component. Many components, such as a dielectric filter [5,9,10], an arrayed waveguide grating [2], a Mach-Zehnder interferometer [11], a long-period fiber grating [12], double detectors [13,14], a semiconductor optoelectronic diode (SOD) [15], and so on, were proposed for monitoring a TLS.…”

Simultaneous monitoring of power, wavelength, and channel number for a tunable laser is demonstrated by use of a combination of an optical isolator, an etalon, a polarizer, and photodiodes. The mode hopping and incomplete-tuning problems that might arise in tuning the laser can be detected with the proposed approach. The spectral response of the monitoring module can be adjusted to match the wavelength-tuning range. The spectral adjustment can be performed by rotating the input polarization or the output polarizer. It can also be tuned by rotating the second stage if a two-stage isolator is used. We demonstrate experimentally the feasibility of this approach by use of discrete fiber-pigtailed components.

“…The second path is used for resolving the channel position among different channels; this requires optoelectronic components with channel-dependent characteristics. Possible candidates include various optical filters, 3,10 tunable FP etalons, 6,7 arrayed waveguide gratings, 8,9 Mach-Zehnder interferometers, 11 long-period fiber gratings, 12 and spectral filtering detectors. 13,14 Here we propose to use the voltage induced across a semiconductor optoelectronic diode ͑SOD͒ for channel recognition.…”

A high-resolution tunable-wavelength controller is achieved by use of an etalon for control of wavelength drift and a semiconductor optical diode (SOD) for channel recognition. The etalon provides a stable wavelength reference, and the SOD can detect mode-hopping and incomplete-tuning problems in tuning a laser. With the help of a Fabry-Perot etalon as a precise wavelength reference, the usual concern with the temperature stability of a SOD can be relaxed at least tenfold compared with wavelength control with a single SOD. We demonstrate the feasibility of monitoring tunable lasers by using a Fabry-Perot laser diode (FPLD) or a semiconductor optical amplifier (SOA). The induced voltage of the FPLD and that of the SOA are modeled with analytic expressions that can help to optimize the operation of a SOD sensor.
