Description
Technical field
The utility model relates to the optical device in fiber optic communication field, particularly the integrated light splitting coupling optical components of one.
Background technology
Integrated is the Main way that optical element develops with miniaturization.As shown in Figure 1.Fig. 1 is the light channel structure schematic diagram of point optically-coupled of prior art.As shown in Figure 1, the light channel structure of point optically-coupled of prior art comprises optical fiber 10, lens 20 and polarization beam apparatus (Polarization Beam Splitter is called for short PBS) 30.Wherein lens 20 comprise the first lens 20a, the second lens 20b and the 3rd lens 20c further.Wherein the first lens 20a is arranged on before polarization beam apparatus 30 along light path forward, and the second lens 20b and the 3rd lens 20c is arranged on after polarization beam apparatus 30.
Incident ray exports the first lens 20a to from optical fiber 10, after collimating via the first lens 20a, become parallel rays and be incident to polarization beam apparatus 30, wherein polarization state is that P Transmission light to the S light of the 3rd lens 20c simultaneously vertical direction of horizontal direction reflexes to the second lens 20b, then, after P light and the focusing of S light respectively through the second lens 20b and the 3rd lens 20c, become converging light and export.
But, in existing light splitting coupling optical path structure, due to collimation and the existence of lens 20 that focuses on, make whole light splitting coupling optical path size bigger than normal, the demand of device miniaturization cannot be met.
Summary of the invention

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model done and further describe in detail.
Referring to the structure diagram that Fig. 2, Fig. 2 are integrated light splitting coupling optical components of the present utility model.Integrated light splitting coupling optical components of the present utility model.
As shown in Figure 2, integrated light splitting coupling optical components comprises the first lens 200a, the second lens 200b, the 3rd lens 200c and polarization beam apparatus 300.Wherein, the first lens 200a, the second lens 200b, the 3rd lens 200c are integrated on polarization beam apparatus 300.
Wherein polarization beam apparatus 300 comprises the first prism 300a and the second prism 300b.Wherein the first prism 300a is set to Tp, and the second prism 300b is set to Dove prism.Wherein the surface of contact of the first prism 300a and the second prism 300b comprises the PBS film with certain splitting ratio, and after light beam enters polarization beam apparatus 300, a part of light beam generation transmission, remaining segment beam reflects.In second prism 300b, the other end parallel with PBS film is set to total reflection film, the segment beam reflected is totally reflected by PBS film.
First lens 200a is arranged on one end of the second prism 300b, and the second lens 200b is arranged on the other end parallel with the first lens 200a; 3rd lens 200c is arranged on the right angle end of the first prism 300a, and parallel with the first lens 200a.
Referring again to Fig. 2, first lens 200a enters polarization beam apparatus 300 after the collimate light coming from optical fiber 100 is become parallel beam, wherein in light beam, the P light of polarization state level enters the 3rd lens 200c via after the transmission of PBS film, the S light that in parallel beam, polarization state is vertical enters the second lens 200b via after the reflection of PBS film, after focussing force via the second lens 200b and the 3rd lens 200c, become converging light and export.
Integrated light splitting coupling optical components of the present utility model has the following advantages and good effect compared to prior art: the first lens 200a, the second lens 200b and the 3rd lens 200c and polarization beam apparatus 300 integrate, technological operation is simple, size reduces, and its optical parametric stable performance.
The above, be only the utility model most preferred embodiment, and not for limiting scope of the present utility model, all equivalences done according to the utility model claim change or modify, and are all the utility model and contain.
