Description

A kind of SOA-R of preventing tube core swashs the method for packing of penetrating

Technical field

The present invention relates to a kind of SOA-R of preventing tube core and swash the method for packing of penetrating.

Background technology

The various devices of SOA-R and module are mainly used in WDM-PON of future generation field, use among the WDM-PON of Wavelength reuse of SOA-R, utilize the gain saturation effect of SOA-R can wipe information in the downstream signal.Just can directly modulate this wavelength then and transmit upward signal.Each wavelength only need be provided with a transmitter at OLT end in entire WDM-PON, has simplified the maintenance and management of network, and to the coded format ' transparent ' of used downstream signal.

The various devices of SOA-R and the making of module depend on a kind of do not swash penetrate the realization of the SOA-R-TO device that coupling loss is little.Penetrate if the SOA-R device exists to swash, the wide spectral characteristics of tube core just cannot be accomplished, and the Wavelength reuse of device just cannot guarantee.

Summary of the invention

The objective of the invention is at above-mentioned present situation, aim to provide a kind of simple in structure, reliable, do not swash penetrate effect, be convenient to assemble, the SOA-R tube core that prevents that coupling efficiency is high swashs the method for packing of penetrating.

The implementation of the object of the invention is, a kind of SOA-R of preventing tube core swashs the method for packing of penetrating, concrete steps are, mount the SOA-R tube core, on SOA-R tube core assembly front end emergent light, add a glass pad, with H20E glue the glass pad is bonded to the TO base top, utilize wave plate principle θ=2 φ, be connected on the glass pad with H20E is gluing behind λ/4 wave plates rotation φ=45 °, the area of λ/4 wave plates at least 1/3 overlaps with the glass pad, make wave plate can cover the laser light-emitting zone fully, be connected on the glass pad with H20E is gluing behind λ/4 wave plates rotation φ=45 ° at last, glue was consolidated in 120 ℃ of bakings in 20-30 minute.

The present invention utilizes wave plate principle θ=2 φ, is connected on the glass pad with H20E is gluing behind the wave plate of λ/4 rotation φ=45 °, prevents to export light reflected back tube core effectively, has prevented the sharp situation of penetrating of SOA-R tube core; Adopting under existing paster technique and the adhering process simultaneously, the coupling efficiency of RSOA-TO still can reach more than 70%.

Embodiment

With reference to Fig. 1, the face that dissociates before the SOA-R tube core 2 has the inclination angle of α=33 °, so emergent light also has the angle of emergence of α=33 °, after the face that dissociates be parallel, so be a parallel emergent light, the present invention is mounted on the transition block 1 with SOA-R tube core 2, the inclination angle that α=33 ° are arranged between the limit, the tube core-transition block assembly as shown in Figure 2 of the tube core component drawings after mounting, like this, emergent light is exactly suitable vertical outgoing, then holds the angle of emergence of emergent light just to be 33 °.

Method for packing of the present invention is: mount the SOA-R tube core, on SOA-R tube core assembly 4 front end emergent lights, add a glass pad 5, use H20E glue that glass pad 5 is bonded to the TO base top, utilize wave plate principle θ=2 φ, be connected on the glass pad with H20E is gluing behind λ shown in Figure 3/4 wave plates 6 rotation φ=45 °, the area of λ/4 wave plates 6 at least 1/3 overlaps with the glass pad, makes wave plate can cover the laser light-emitting zone fully.Be connected on the glass pad with H20E is gluing behind λ/4 wave plates rotation φ=45 ° at last, θ=90 ° like this, the light that promptly returns and the light of incident is quadrature just, the polarization of incident light attitude is more near linear polarization, the interaction of the light that returns and the light of incident is just more little, thereby has prevented the sharp situation of penetrating of SOA-R tube core.

Adopting under existing paster technique and the adhering process simultaneously, the coupling efficiency of RSOA-TO still can reach more than 70%.

SOA-R-TO after mounting as shown in Figure 4, visual inspection behind 20-30 minute solid glue of 120 ℃ of bakings, it is bonding firm to confirm.The spontaneous radiation spectrogram of SOA-R-TO by mounting the 7 back outgoing of non-globe lens cap is a kind of smooth as shown in Figure 6, do not have the spectrum that swashs lase; And do not have to utilize the SOA-R tube core add λ/4 wave plates 6, the spontaneous radiation spectrum of outgoing as shown in Figure 5, spectrum has significantly to swash penetrates phenomenon.
