wafer probe station for research and development with dc, Rf and
optical coupling to the wafers and thermochuck.
Launched at OFC, the system uses a non-contact
optical coupling which, the company says together with the connector design, helps to provide reduced sensitivity to dust.
The use of
optical coupling, most commonly seen in smartphones, also minimises reflection and eliminates air gaps and their associated issues, such as debris and moisture.
It has been proved in our previous works [28-31] and other reports [32-34] that the ultrathin Ag film with a suited
optical coupling layer could meet the requirements of a transparent electrode.
While the analysis was successfully performed on a detection volume < 1 [micro]L, the
optical coupling losses between components caused a 53.9% optical loss per pass.
According to the Bragg condition, the incident angle 0 of the grating coupler has considerable influence on
optical coupling. To facilitate system integration, most studies aim to reach [theta] = 0[degrees] with a high coupling efficiency and a wide bandwidth.
Among the state manipulation, Rabi oscillation is a fundamental phenomenon by coherent
optical coupling, which provides a direct control to the state population and coherence of a quantum system.
Figure 3 shows (a) the scheme of the
optical coupling and (b) pictures of the Sci-Fi and clear fibers prepared for coupling.
The
optical coupling and decoupling structure does not need to be linked to an optical source or spectrometer.
This instrument incorporates Horiba's confocal LabRAM Raman microprobe, which features a stable mechanical coupling and an efficient
optical coupling. It can be used to apply ultraviolet, resonance Raman, plasmonics and laser fluorescence.
Conventionally, efficiently transmitting optical signals between opto-electric converters and optical fiber (
optical coupling) required an
optical coupling unit that consisted of a lens component and an optical connector (Figure 3).
FiberZone's AFM product line utilizes patent-pending Latched
Optical Coupling (LOC(TM)) technology that delivers reliable passive connectivity in a remotely-managed automated fiber management system.
