摘要： Techniques for designing optical devices with high isolation are disclosed. The high isolation is achieved by causing a reflected light signal to go through another filter. According to one embodiment, an optical apparatus comprises a first optical filter configured to transmit a first selected wavelength and reflect all other wavelengths, a second optical filter the second optical filter configured to transmit a second selected wavelength and reflect all other wavelengths. The first optical filter, being not perfect and producing a reflected signal with a residual of a signal at the first selected wavelength, the residual of the signal is minimized by the second optical filter when the reflected signal is impinged upon the second optical filter.

摘要： Techniques for calibrating tunable optical devices using a probing signal as a reference so as to achieve an accurate control over an absolute wavelength of the tunable optical devices. A probing signal being a calibrated optical signal with a spectrum centered at a desired add/drop channel or wavelength is introduced into an N-port circulator coupled between two tunable optical devices. When the two tunable optical devices are tuned not exactly at the desired wavelength, a portion of probing signal will be reflected or dropped out by the two tunable optical devices. The dropped probing signal is detected and coupled to a signal processor or circuitry configured to generate adjustments to or the control signals for controlling the tunable optical devices in accordance with the reflected probing signal being maximized.

In one embodiment, for example, a free-space optical collimator includes a base having a length, a generally flat bottom surface and a top surface. A groove is disposed along the top surface of the base extending through the length of the base. A lens is disposed within the groove of the base and a fiber optic pigtail is disposed generally adjacent to a focal point of the lens. The lens and fiber optic pigtail are aligned within the groove to reduce an off-angle offset of an optical light signal propagating through the free-space optical collimator. In other embodiments, a process of producing a free-space optical collimator is also provided.

摘要： Disclosed herein is wavelength-division multiplexing (WDM) and demultiplexing with signal entry and exit in a common routing surface to increase channel density. In particular, disclosed is a WDM assembly including a plurality of common ports and a plurality of channel sets having one or more channel ports. The WDM assembly includes a first routing surface with a first WDM passband and a second routing surface offset from the first routing surface. The second routing surface is configured to reflect at least one signal passed through the first routing surface back through the first routing surface at a laterally different location. Optical signal paths of at least a portion of the common ports are parallel to and offset from one another. In certain embodiments, such a configuration may increase channel density and decrease a form factor (e.g., footprint).
